When Zhengyu lost his original number one position because of Ha Na's sudden rise, his heart was filled with unwillingness and frustration.In order to regain that honor, he launched a fierce competition with Ha Na.However, in this seemingly simple contest, both men paid a huge price - they fainted due to overexertion and were rushed to the health room.Ha Na's tenacity is shocking. Even after fainting, she still recited the list and even left early to attend the cram school lecture.

Time flies, when Jung Woo and Ha Na meet again, the air is filled with embarrassment and uneasiness.They decide not to be near each other anymore, trying to put the ghosts of the past behind them.However, the red thread of fate seems to have already closely connected them.Ha Na's mother gave Ha Na the medicine, apologized for it, and even held a depression party for Jung Woo.At this party, the lawyer brought exciting news - Dean Jiang Zhenshuo, an anesthesiologist, will appear in court to prove Zhengyu's innocence.However, Zhengyu was a little confused by the news.

Just as Zhengyu was trying to adapt to his new life, a sudden accident broke the peace.A man broke the glass of Zhengyu's house. This incident was discovered by Ha Na's brother Bodo and triggered a police investigation.Nan's mother invited Zhengyu to live in their house temporarily, but Zhengyu declined politely.However, while cleaning up the broken glass, he accidentally cut his hand.Seeing this scene, Ha Na felt a surge of complicated emotions in her heart.She insisted on letting Zhengyu live in their home, and Ha Na's mother was even more happy after discovering that the two were classmates.

In the days that followed, the relationship between Zheng Yu and Ha Na gradually heated up.They bought ice cream, tasted spicy rice cakes and even went to an amusement park together.Ha Neul admitted that she never sang pop songs, and Jung Woo suggested that since both of them had fallen, they might as well stop and take a rest.

However, life is always full of variables.Ha Na suddenly discovered that her severance pay was pitifully small. It turned out that she had been treated as a contracted employee by the professor.Jung-woo encourages her to stay calm, otherwise she will have trouble establishing herself in this industry.Ha Neul went to her colleagues for confirmation, but her colleagues were unwilling to pursue the case and even hoped that she would not show up again.

Bo-do helps fix the window, but Jung-woo overhears Bo-do and his mother discussing him while saying thanks.They think Zhengyu should not continue to live there.Ha Na noticed Zheng Yu's depression, and the lawyer's call made matters worse - Zhen Shuo suddenly refused to testify.Jung-woo anxiously looks for Jin-seok, but learns that he has resigned.The depressed Zheng Yu went to drink to relieve his sorrow, while Ha Na stayed up all night and finally found a patient with the same cause of death as Cang Bing.

When the day of the second trial arrived, Ha Neul hurried over with evidence, but the prosecutor did not accept it.Afterwards, reporters surrounded Jung Woo, while Ha Na fell and was injured in the chaos.Zhengyu took her to his clinic for treatment without hesitation.Ha Na suggested playing all night, but Jung Woo suggested going to Sokcho to watch the sunrise.Despite the bad weather, the two were unable to see the sunrise, but their hearts became more closely connected because of the experience.Jung-woo asks Ha-neul for her phone number, hoping they can become friends.

Recalling the past, Ha Na once left a note to encourage Zheng Yu, but she overheard the conversation between Zheng Yu's mother and the teacher, saying that Zheng Yu was embarrassed.This secret has been plaguing Ha Na, making her feelings towards Zheng Yu complicated and contradictory.
