The Oath of Love

Dr Gu is popular with his patients but antisocial otherwise. Lin Zhi Xiao's encounter with Gu at a bar causes some awkwardness when she runs into him again at the hospital.

Zhi Xiao and her mother try to keep the severity of his condition a secret from her father. Meanwhile, Zhi Xiao tries to convince Dr Gu to take over her father's operation.

The person who started the fundraising at the hospital turns out to be Gu Wei, who usually seems cold-hearted and cold-faced. Lin Zhi Xiao begins to change her mind towards Gu Wei.

Zhi Xiao is determined and follows Gu Wei everywhere in the hospital. When she takes a blow meant for him, he gently addresses the wound.

Gu Wei helps Lin Zhi Xiao search for her father around the city. Dr. Gao realizes that Dr. Gu is falling for Zhi Xiao.

Zhi Xiao, her father, and Gu Wei have a meal at KFC per the father's request.

Zhi Xiao is excited to get the lead cello for the next performance. Dr. Gao looks for Dr. Gu only to be told that he was with Lin Zhi Xiao.

Gu Wei attends the recital and defends Lin Zhi Xiao when other orchestra members try to belittle her. Dr. Gu's parents invite Dr. Gao over for dinner.

Gu Wei looks for an apartment for three purposes: to find a place to live, to stop Zhi Xiao from practicing cello before her hand recovers, and to spend time with her.

Gu Wei's parents waylay him from his appointment to sign a rental contract. Zhi Xiao writes up a proposal for another apartment but is told that he will move with Dr. Gao.

After entering his house, Gu Wei asked Lin Zhi Xiao to take a shower first. Lin Zhi Xiao gets some wild thoughts about the breath-freshening candy that is essential for kissing.

Gu Wei also started searching for Shao Jiang after returning home, but saw reports about "genius violinist" filling the screen.

Shao Jiang's words made Gu Wei very unhappy. Seeing Gu Wei's uncharacteristic behavior, Gao Xi couldn't help but blame him for mistreating Lin Zhi Xiao.

Dao Li catches up with Lin Zhi Xiao and sees her weak appearance, so he simply picks her up and taker her back to his home.

After Lin Zhi Xiao returns home, she studies the Coke she received for a long time. She really couldn't figure out what Gu Wei meant, so she can't dare to drink it.

Gu Wei knew that he was going on a date with Sansan, and asked Sansan if this counts as being together, but he was scorned back.

After returning from the date, Lin Zhi Xiao followed the example of Yinxi and Jinshi and bought couple clothes online.

At night, Gu Wei gets so angry that he can't sleep and doesn't reply to Lin Zhixiao's good night message.

Sansan asks Lin Zhi Xiao to go to the suburbs to play together. Lin Zhi Xiao packs her bag, but finds that Gu Wei is waiting for her.
