Katagiri Kyosuke, who came to Beijing from somewhere to attend college, is in a long-distance relationship with Saachi Koyamauchi.However, by chance, he met Kunikida Murasaki, a married woman who lives next to his apartment, and had a physical relationship with her.

The continuous unfolding of immorality had no resonance at all with Kyousuke's way of dealing with two women, but instead, it became a habitual love story.I don’t know whether the man I really love, Kyousuke, will choose a local girlfriend or a married woman in the city? What will happen to the shattered love that starts with incest?

Katagiri Kyosuke left his hometown to live alone in Tokyo in order to go to college.In his hometown, he is in a long-distance relationship with his girlfriend Sachichi Koyamauchi, whom he has been dating since middle school, and leads a stable college life.

On the other hand, Saichi writes a letter to Kyousuke, looking forward to the day when Kyousuke replies.Almost another year has passed like this.

One day, Kyousuke sent a lost item he picked up by chance to his neighbor's room.What came out was Kunikida Murasaki, a mature woman who had just taken a shower and was full of charm.Kyosuke didn't know where to look, so he left the room.

Since that day, Purano had greeted her several times, but she met her where her husband was and learned about the marriage.Although Kyousuke had always been disgusted by what he said, Murasaki's words made Kyousuke take the first step...

After spending the night with Murasaki, when Kyousuke returned to the room, there was a knock on the door through the wall.Kyousuke came to Murasaki's room again, and soon, their bodies overlapped again.

Saichi, who knew nothing, confided in his friends that he had been dating Kyosuke for many years but had no physical relationship with him.Saachi was told about the dangers of long-distance love in such a relationship, but showed that he didn't care...

In college, Kyousuke was told something meaningful by his classmate Asahi.Kyousuke was very concerned about what the frivolous Asahi said.Moreover, Asahi saw Kyousuke and Murasaki buying condoms at a convenience store...

Saachi continued to write to Kyousuke while feeling uneasy about not receiving a reply.But just waiting is not enough, Saachi decides to go to Tokyo without telling Kyousuke.On the other hand, Kyosuke and Murasaki's relationship has normalized and they are unable to reply to Saachi's letter.

When Kyosuke came back from college, Murasaki and Saachi appeared in front of the room...Saachi was startled by this sudden incident, but Kyosuke greeted him as if nothing had happened.

That night, when Kyousuke was taking a bath, Saachi seemed to hear a knock on the wall and put his ear closer.At this time, Kyosuke found the condom dropped under the bed.

Kyosuke watched with mixed emotions as he watched Saachi walk towards the station while saying he wanted to reply.

During the group project in class, Kyosuke and Misuzu Sukawa formed a pair, and Misuzu discovered a hickey on Kyosuke's neck.

When Saichi returned to his hometown, he told his friends that he had not had sex with Kyousuke. His friend said that Saichi might be venting his emotions elsewhere.Saachi, who believed Kyousuke, firmly denied it.

In this case, Kyosuke did not go to school because he had a cold.Purano came to Kyosuke, and Mei Ling and Purano met and couldn't help but ran out.

After Kyosuke woke up in the hospital after falling down the stairs, he found Saichi looking at him with an uneasy look on his face.

Saachi learned from Misuzu that Kyousuke was hospitalized and hurried to Tokyo.Then, Kyosuke went to the apartment alone to get a change of clothes, and was preparing the things he would need for hospitalization when Murasaki came.Murasaki heard that Kyousuke was hospitalized and helped Saachi find a change of clothes.

On the other hand, Kyosuke told Meiling about his childhood when he came to the hospital to visit.Moreover, when talking about meeting Saachi, Kyousuke seemed to have discovered his true feelings...

Saachi, who was bid farewell by Kyousuke, ran out of the ward from that place as if running away.After hearing this, Misuzu blamed Kyosuke, leaving him speechless.

Saachi returned to his hometown in this way. Although he was very strong in college, Isesaki realized that something was wrong with him and told him everything.

On the other hand, Kyousuke, who was discharged from the hospital, was asked about Saachi by Murasaki.Later, Kyousuke found Saichi's forgotten cardigan in the room. Although he wanted to give it away for a while, he never made up his mind...

One day, Kyousuke appeared in front of Saachi who was returning home from college...Seeing that figure, Saichi couldn't help but run...

Kyosuke, who feels affection for Saachi, tells Murasaki that he wants to end the physical relationship.However, Murasaki's husband used a surveillance camera to see that...

When Kyousuke was drinking with his friends, Misuzu asked Saichi if he truly forgives Kyousuke for cheating on her.Misuzu's words made Kyosuke fall into deep thought.

Kyousuke went home alone and called Saachi in front of the apartment.Hearing Saichi's voice, Kyosuke smiled, but Murasaki and Kaname returned home.Saachi heard Murasaki's voice through the phone and tried to be cheerful...

Kyousuke didn't receive Saichi's letter and seemed very disappointed.At this time, Zi Naihe was belatedly arriving.Kyousuke greeted each other, but the key to his smile was the strange look in his eyes.

On the other hand, Saachi, who was worried about Kyosuke alone, acted strong with the encouragement of Isezaki, but after getting worried, he sent a message to Kyosuke that he wanted to change the barbecue schedule.

Under such circumstances, Murasaki returned to the main house. She stared at Murasaki...and then the next morning, she suddenly appeared in front of Kyousuke and uttered a shocking sentence!

Kyosuke, who plans to sever ties with Murasaki, demands compensation after knowing everything.In order to pay off the debt, Kyousuke works part-time every day and is unable to reply to Saichi's text messages. Saichi, who is unaware of this, only feels uneasy.

On the other hand, Murasaki, who returned to the main house, was also asked by Okabe about her relationship with Kyosuke.Although Purano was a little shaken, she still wanted to protect Kyosuke, so Purano suggested that the key was to terminate the apartment contract so that everything would disappear.

Under such circumstances, when Sachichi went to Kyousuke's coffee shop to drink tea, Kaname and Murasaki accidentally appeared in front of the two of them! Kyousuke and Sachichi were forced to sit at the same table by Okabe...

After Saichi (Nakayama Nana) broke up, Kyosuke (Kimura Keito) began a life of self-destruction. He neither attended university classes nor went to work, and spent every day in a muddle.One day, when Asahi (Nose Ton) saw the mediation agreement sent to Kyousuke by Kaname (Michi Sakurada), Kyousuke's mood became even lower.

Misuzu (Hina Higuchi), who is worried about Kyousuke's increasing depression, tries to invite him to have dinner together in the hope that he can cheer up, but Kyousuke's life is becoming increasingly desolate.

On the other hand, Murasaki (Rei Ishikawa) received a call from Kaname's subordinate and learned about Kaname's performance at the workplace.This was completely different from what he usually saw at home, which surprised Murasaki.

Kyosuke (Kimura Keito) holds the last letter sent by Saachi (Nakayama Nakayama) in his hand. The edges of the envelope have been worn white, but he still can't muster the courage to open it.Whenever it was late at night, Kyousuke's heart was filled with endless regret and guilt. He was afraid that the words in the letter would become pain that he could not face.

After Murasaki (Rei Ishikawa) learned that her husband had made something like a settlement letter, she experienced a fierce inner struggle.She knew that this might be an opportunity to redeem Kyousuke. She was willing to pay the settlement money on Kyousuke's behalf, but was rejected by Kyousuke. Purano felt unprecedented frustration and powerlessness.She looked at Kyousuke's back, and an indescribable complex emotion surged in her heart, including sympathy for him and anger at her own powerlessness.

After Kaname (Michi Sakurada) was revealed by Murasaki that he had been spying on her, a trace of panic flashed in his eyes.To start telling his past, with a tremor in his voice, he confessed that the reason why he did this was because of the persistence and love for Murasaki deep in his heart.Zi Nai was also shocked. She did not expect that there was such an emotional entanglement behind Kaname's behavior.

Saachi, on the other hand, has been in a trance after his sad separation from Kyousuke.Her heart was filled with fear for the future and nostalgia for the past.After realizing that she could no longer sink like this, Zaozhi decided to complete something of great significance to her while her memory was still clear.She hopes to use this action to bring an end to this relationship, and at the same time, it is also a kind of relief for herself.

In front of Murasaki (Ishikawa Ren) and Kaname (Sakurada Tsuri), Kyousuke (Kimura Keito) once again negotiated the settlement fund, and finally the two parties agreed to spend four years to pay the settlement fund.Soon after graduating from Kyosuke University, I worked in a publishing house.Four years later, the settlement was finally paid off.During this period, Kyousuke wrote several letters to Saachi (Nakayama Nano)...

Time flies, and it has been 8 years since I graduated from college.Kyousuke moved out of the apartment he had been living in and started living in a new place. He accidentally met an elementary school student who called himself Aming.This kid says he misses him for some reason

That kid is actually...
