改编自同名网络漫画的《善意的竞争》是一部悬疑心理惊悚片GL(Girl Love)作品，讲述了曾是高考出题委员的爸爸突然去世后，转学到首尔名牌女高中的涩琪与全校第一名也是实权人物Jay成为朋友，但越接近Jay，她的内心和死亡秘密就越来越暴露。

禹瑟琪变成失踪儿童的故事虽然有点搞笑，不过她的故事转折却也涵盖了这社会的许多写实，透过禹瑟琪被当隐形人，又或者是她被霸凌，导演刻画了这社会对没有突出表现的人就不会有注意的常态，更是突现社会的注意力只在权力地位人物身上的现实；然后镜头换到禹瑟琪本是被当空气，却因为“太过平凡”而被讨厌～ 禹瑟琪的翻身是靠着“读书”来逆转的，但读书的方式就是非常“偏执”，靠着吃药让自己疯狂念书。但我觉得禹瑟琪追求的不是第一名，而是第一名背后带来的“被尊重”，这当然就牵涉到这社会看待一个人的表浅和利益价值（例如育幼院看到禹瑟琪的成绩突飞猛进，晚餐不再被忘记，甚至还可以享受冷气！）。学校就是小型的社会，就跟我们现实生活中的社会一样，我们何尝不是都想要在工作地位可以有一席地，然后得到别人对自己的尊重。说白话一点，禹瑟琪一定要第一名的这种偏执就来自于“这社会”对她这种没有任何价值可以提供的人物“毫不理会”（看看禹瑟琪因为没有家长陪同，连老师都不理她，毕竟家长在学校里可以“人脉”的象征，毫无背景的禹瑟琪在这圈子里就毫无存在感）。

在伊买下老奶奶的全部花束的那场戏，对比到禹瑟琪，也形成对比的画面，禹瑟琪虽然内心充满不舍可是她就没钱可以跟奶奶买花，对比到刘在伊帅气地掏钱，还有在入学典礼这里讲到“成为我刘在伊的学妹将会是各位的荣耀”这样话语，导演透过这场戏展现出禹瑟琪这个丑小鸭和学霸富家女之间的地位显著差距。当所有人都渴望可以和在伊攀上点关系时，禹瑟琪却被在伊给盯上～这是为什么呢？剧情中都是透露著在伊是故意选择瑟琪的，但为什么选择她，我们文章之后会讨论到。另外，本剧的重点是“GL”，这跟我们想像一般的学校竞争韩剧不同，讲述的是禹瑟琪和在伊之间的感情火花，只是在刻画在伊对禹瑟琪情感的时候，本剧是用有点悬疑和惊悚的方式来展现，透过有些紧张的配乐，总会让观众疑惑著在伊对禹瑟琪的好意和关心好像“不怀好意”以及“心机”的错觉感。虽然浏海女说被在伊选中的话就无法正常过生活，可是我觉得在伊应该不是指使大家欺负别人的人，而是那些为在伊争风吃醋的人在离间那些在伊选中喜欢的人主动离开在伊，这也是为什么刘娜莉会说“以为自己被在伊选中就当自己是灰姑娘了吗？”，这样浏海女很可能也曾经是被在伊给选中喜欢或亲近的人，结果被那些想对在伊攀炎附势的人们给霸凌。第二集禹瑟琪再度被霸凌，这场景是在呼应到禹瑟琪的心魔，她会拼命想要考第一是为了摆脱被霸凌、不想要被看不起的命运，所以她现在来到这高中，更是要拼命摆脱。

第三集里着重于刻画在伊这个角色故事线上，虽然靠着读书得到爸爸关注，但也是一种诅咒，身上的那身盔甲我觉得是一种隐喻，是象征着父亲在她身上塑造的一种别人都无法伤害她的武装，剧情里说到在伊有一场梦是让自己坠落汉江，这样就可以摆脱父亲的诅咒，以及免于姐姐杀掉自己。至于这方法是什么？我觉得就是“找机会毁掉爸爸”，其实透过小京的话语讲到在伊的爸爸很奇怪，还提及在伊的姐姐都没消息，老实说禹瑟琪的爸爸当考试委员会死掉，案情我也觉得不单纯（刘泰俊是禹道赫替败血正紧急送医时的医生）。

然后禹瑟琪还觉得奇怪，自己都还没自我介绍就在伊就已经知道她的名字，在伊也显得对禹瑟琪的过去很了解，因为我觉得当初在伊会选择禹瑟琪很显然是那个韩国大学的吊饰（很可能是她知道那个吊饰就是从生父来的）。总结起来，在伊应该故意接近和选择禹瑟琪，然后对禹瑟琪好，这样在在禹道赫的案件上可以证明父亲什么罪行，毁掉父亲，这样在伊身上的束缚与诅咒就可以解开，在伊也不必担心姐姐一直想杀掉自己，在伊还能享受做自己的自由。

The symbol of Yu Seqi's story of becoming a squad leader is: ❶ Yu Seqi gains power in this class, because being a squad leader is an important figure in determining the big and small things in the class, especially when Yi Zheng asks Cui Jing to apologizeWhen I asked, I specifically asked “ right, squad leader?”, and then Yu Seqi continued smoothly. This scene highlighted Yu Seqi's status in this class after gaining power; ➋In addition, the scene of Yu Seqi becoming the squad leader is actually at the same timeIt is a metaphor that Yu Seqi falls into Yi's plan and trap without knowing it. This is actually a bit of a reverse suggesting that the character Jae-yi wants to help Yu Seqi portray it like this. If I think it right,I think the person who made the vote is Jae Yi, which shows that Jae Yi needs Yu Seqi to trust and rely on her. As for what are the benefits of such a purpose in Yi?As I reasoned in the previous paragraph, Jae Yi wanted to use Yu Seqi's father's death to defeat his father and destroy him, so that Jae Yi could have freedom.Especially in this episode, it is particularly mentioned that Yu Seqi's father's death is suspected to be a medical negligence, and even the administrative director went to Yu Seqi's house to talk to her mother about the % settlement. I believe this matter isYi must have mastered it. I think the original intention of Yi was not only to use Yu Seqi to destroy his father (this is why there has been information on Yu Seqi's investigation on Yi's mobile phone, so there is a princess in Yi.In fact, it was prepared on purpose by Yi Yi, who wanted to deliberately pretend to have something in common with Yu Seqi so that Yu Seqi could believe her), but on the other hand, Yi Yi's original intention might not be bad, and she wanted to help YuSeqi gets the truth about her father's death.

The perspective of episode 5 is shifting to more characters (mostly, the screenwriter begins to design different characters to master the interweaving of other people's secrets and handles), ❶Choi Kyung is the second place in “ Wannian behind Yi, this is a storyline.When Cui Jing found out that Jae Yi's father was actually in a lawsuit, the scheming to defeat Jae Yi came out, especially when I helped Yu Seqi become a ticket and became the squad leader, which made her even more annoying Jae Yi to let her againIt is ” deputy squad leader %!And now that Jae Yi’s father has the handle, I think this will be the way she uses to threaten Jae Yi.➋On the other hand, it is also very interesting, that is, Yu Seqi discovered Jae Yi's true face and secret, such as the secret of Jin Nali being threatened to transfer to school by Jae Yi, ❸ Zhu Yili stole Yu Seqi's short article to let everyone know YuSeqi doesn't want to disclose the secret that she is an orphan.The small movements and interweaving between these characters start at episode 5~

Cui Jing took the initiative to find Yu Seqi and confirmed to her that her father was the key figure in the case her mother was working on.Then, Cui Jing elaborated on the whole story of the litigation to Yu Seqi in detail, and pointed out that Liu Zaiyi's real purpose in approaching her was to settle the case privately.Cui Jing admitted that the reason why he helped Yu Seqi so actively was actually due to his inferiority complex towards Liu Zaiyi.

After Yu Seqi returned home, she began to search for the cabinets at home frantically, hoping to find documents related to medical litigation.Although she once considered confessing to her stepmother, she finally chose to remain silent because she wanted to continue living in this home.

As the midterm exam approaches, Yu Seqi feels the pressure is increasing and she begins to need medicine to extend her study time.However, she visited several clinics and was told that the medication must be prescribed.In desperation, Yu Seqi could only look for sellers on the online platform.What surprised her was that when she made an appointment with the seller, she found out that the other party was Liu Zaiyi.

Zhu Yili took the initiative to find Liu Zaiyi's father, revealed the truth that Liu Zai Na did not go out to study, and hinted that she had a secret that he could not say.She hopes to get some benefits from Liu Zaiyi's father in exchange.

At the same time, Yu Seqi's gangster brother in the kindergarten suddenly appeared at her school, threatening her to hand over the medicine she had hidden before, otherwise it would be detrimental to her by next week.This made Yu Seqi panic.

In the midterm exam, Yu Seqi and Liu Zaiyi tied for the first place, and the top 20 students will have the opportunity to get a health check from J Hospital.This made Yu Seqi very worried because she was worried that the reaction of medication would be detected.In desperation, she knelt down to Liu Zaiyi to show weakness, but Liu Zaiyi said that she had been helping Yu Seqi and did not intend to use the private settlement of medical disputes to threaten her.

However, when Yu Seqi asked Liu Zaiyi how she obtained her data, Liu Zaiyi made her previous agreement: if her midterm exam scores are better than Yu Seqi, she will tell the truth.Now, she seemed ready to fulfill the agreement.

At the school anniversary of Caihua Girls' High School, the four girls - Liu Zaiyi, Yu Seqi, Zhu Yili and Cui Jing, as well as their respective relatives and friends, were intertwined by a series of unexpected events, as if they were pulled by invisible forces.Same stage.

Liu Zaiyi and Yu Seqi's intimate interactions are particularly eye-catching.They wore ribbons on their heads, laughing and laughing, and their intimacy between them was in sharp contrast with their past alienation.Bystanders couldn't help but speculate: Have “ of them already settled their past grudges?”After all, the relationship between the two was as cold as a stranger, and the harmonious scene now is indeed surprising.

Then, Liu Taijun's appearance triggered another climax.When he met Liu Zaiyi and Yu Seqi, his eyes were as sharp as a knife, locking tightly on Yu Seqi, as if he had a thousand words to say but he could stop.After all, Liu Taijun already knew that Yu Seqi was the daughter of Yu Daohe who died in his hospital in the past. This origin made him full of complex emotions and doubts about Yu Seqi.This subtle sense of tension permeated the air, causing the whole scene to be shrouded under a mysterious veil.

The interaction between Liu Taijun and Zhu Yili is also exciting.The two once reached a deal because of Liu Zai Na's secret, and now Liu Taijun has given Zhu Yili a special mission.At first, Zhu Yili thought it was just a slight effort, but unexpectedly encountered unexpected twists and turns and crises during the execution.This makes people wonder: What kind of task did Liu Taijun give to Zhu Yili?How will she get rid of danger and get out of danger?

In addition, Choi Kyung's appearance also added a touch of brightness to the school anniversary.She missed her health checkup because she focused on her studies, but she shone brightly at the school anniversary site, attracting everyone's attention.Her appearance undoubtedly injected more vitality and enthusiasm into this event.

Finally, the appearance of Nanbing Town has also become a hot topic for everyone.

Liu Zaiyi's sister Liu Zai Na has been guarding her since childhood. Even if she knows the answer to her homework, she deliberately answered wrong out of protecting her sister.However, in this comparison, Liu Zaiyi gradually surpassed Liu Zai Na.

In order to improve his grades, Liu Zai Na ventured into the teacher's office to steal the midterm exam paper, but was accidentally caught by Yu Seqi's father Yu Daohe.In order to prevent Yu Daohe from revealing this matter, Liu Jae-na took the initiative to approach him.

Liu Zaiyi came to the photocopying room according to the video guidance on her mobile phone, but unexpectedly met her sister Liu Zai Na.While competing for the phone, the two accidentally dropped it out of the window.Liu Zai Na jumped into the window to pick it up without hesitation, but was discovered by the school worker and fled in a hurry. Liu Zai Yi successfully retrieved her cell phone.

Jin Fanxiu became in a trance after taking the medicine. In addition, Zhu Yili casually promised to arrange friendship for her if she found the charger. However, after Jin Fanxiu tried hard to find the charger, she ignored her due to the loss of her phone.Finally, Jin Fanxiu, who could not bear it, tried to hurt Zhu Yili with a knife, but accidentally caused Yu Seqi to be injured.

Yu Seqi was rushed to J Medical Center where Liu Zai Na’s father is located.After learning the news, Liu Zai Na rushed to the hospital immediately.In the operating room, Liu Zai Na tried to suture a wound for the first time with her father's encouragement.

However, when Yu Seqi woke up, Liu Zai Na pushed her to take a walk and chat.Unexpectedly, Liu Zai Na's words seriously hurt Yu Seqi's father made Yu Seqi turn her back on her face in an instant.

The murder weapon melee incident involving Jin Fanxiu actually evolved in an unexpected direction.Yu Seqi, who was originally injured by a weapon on the celebration day, was mistakenly regarded as an attacker.

The students of Caihua Girls' High School are now being questioned by the police one by one.On the day of the celebration, Fan Xiu fell into a trance because she took the medicine provided by Zhao Yala, and then picked up the murder weapon and attacked Zhu Yili and Seqi.

Now, Seqi has been discharged from the hospital with a wrist guard and has a face-to-face confrontation with Fan Xiu.Fan Xiu was accompanied by her parents and lawyers, while Seqi sat alone on the side. This sharp contrast caused many questions.At that time, many witnesses witnessed Fan Xiu's crazy behavior with their own eyes, and some even recorded the whole process.

In order to find the missing Jaina, Jaeyi and Seqi decided to join forces.They abandoned past suspicion, established trust, and embarked on a journey of searching together.At the same time, the police investigation work is still in full swing in the case of illegal drug circulation in Caihua Girls' High School.

The five people jointly determined that only by finding Zaina can the mystery be solved.Byung-jin revealed that Jae Na held the fake ID card he was looking for and belonged to Soo-jin in his hands, and explained the urgency of finding Jae Na.But at this moment, Jae Yi received the news that Jae Na had passed away. She and Seqi immediately took Bingzhen's car to the hospital mentioned in the notice.

Facing the body of Jaina whose face was so damaged that it was unrecognizable, Jae Yi was deeply hit.Seqi hugged Zaiyi tightly and comforted her softly: “ Zaiyi, it's not your fault.”Seqi noticed burn marks on Na's instep, which reminded her of the nursery senior Xiuzhen, who also had the same scars, so she began to look for Xiuzhen's traces.At the same time, Yili and Choi Kyung found the residence of Jae Na before her death - an examination house.

Although the three people tracked different goals, fate led them to meet unexpectedly in the examination hall.Seqi learned from the other people that Soo-jin had passed away, while Yeli and Choi Kyung used the keys they found in the medical club room to open Jaina's room.In the room, from college entrance examination math killer questions to various difficult questions, the walls were filled with densely written, and the scene in front of them shocked the three of them.

Liu Zai Na's funeral is about to be held. This is not only a mourning for the deceased, but also a arena where all forces are secretly competing.Yu Seqi was full of doubts about Jae Na's death, and everyone who came to attend the funeral had their own thoughts, which made the whole atmosphere extremely tense.

On the survivor's seat, Yoo Jae-yi and Yoo Tae-jun became the focus of everyone's attention, and the always mysterious mother, Jung Eun-kyung, finally showed up at this moment.However, there was no trace of sadness or emotional fluctuations on the faces of the three of them, as if they had long been accustomed to this kind of scene.

Seqi, Zhu Yili and Choi Kyung also came to the funeral site. The grudges and disputes between them have not yet been resolved, which adds a bit of gunpowder to the funeral.Seki's father died because of Jae Na, Yeli tried to use Jae Na to achieve her goals, while Choi Kyung knew the relationship between Jae Na and Dohyuk very well.

At the same time, Do Hyuk's wife Kwon Hee-yun, as well as Choi Kyung's mother, Kang Ji-yeon, who is a litigation lawyer, also chose to appear at this critical moment.They are about to obtain key information closely related to Dohe's death.

Liu Taijun's dark side was pursued by Liu Zaiyi and Yu Seqi. They were originally investigative partners who worked together, but unexpectedly embarked on different directions on the road to exploring the truth.When facing many difficulties that were far beyond expectations, Yi began to shake his position under the strong pressure of Liu Taijun and chose to retreat temporarily.

Through the diary left by Liu Zai Na, Seqi gradually pieced together all the suspicious aspects of her father Wu Daohe's death on the day of the operation.With Yi's help, they successfully obtained Dohe's X-ray from Taijun's office, which clearly showed the college entrance examination questions capsules he swallowed during his lifetime.However, this evidence alone is far from enough to make Taijun's crime a sure thing, and the only key figure who has the potential to uncover all the truth - Jae Na, has become their most important breakthrough point at the moment.

Jae and Seqi firmly believe that Taijun will hide Jae Na, so they join forces to track her.

The final exam for Caihua Girls' High School arrived as scheduled, and the students became uneasy.Liu Zaiyi, Seqi and Choi Jing have different expressions.Jae Yi frowned, as if she was not very satisfied with her grades; Seqi lost her former vitality and seemed extremely depressed; while Choi Jing looked relaxed and happy, as if the ranking was not a problem for her.Liu Zaiyi, the first in the school in the midterm exam, is in sharp contrast to Cui Jing, who always follows closely.And the development trend of the murderous weapon melee that Jin Fanxiu was involved in was beyond everyone's expectations.Yu Seqi, who was originally a victim, was mistakenly accused of being the perpetrator.

Next, the camera turns to a photo of Liu Zaiyi and her father Liu Taijun.Recalling the promise that Zai once made to his father: “I will become your pride.”However, her failure to maintain the throne of the top school is undoubtedly an unacceptable setback for Taijun.

As for Zhu Yili, money seems to have become the only driving force in her life.She and Nam Bingzhen had worked together, and this time, the two seemed to be officially forming an alliance.On the other hand, Yu Seqi's behavior began to change.In the past, Liu Zaiyi took the initiative to find her, but this time, she decided to take the initiative to find Liu Zaiyi.The two agreed to meet by the pool.
