Bok-joo pays the clinic fees and gets an examination, but is warned not to overdo it. Bok-joo wants to thank Jae-yi for lending her his umbrella.

Joon-hyung runs into Bok-joo when he visits Jae-yi at the clinic. Bok-joo hides the truth from Jae-yi and explains that they are just old classmates.

Bok-joo is delighted to get a ride from Jae-yi after the concert. While Joon-hyung is in counseling he recalls an incident from his childhood.

Bok-joo's coach and manager find out she is going to a weight loss clinic and tell her father, who is furious. Bok-joo tries to apologize.

Shi-ho snatches Bok-joo's phone away while she is speaking with Joon-hyung. Bok-joo sleeps in a different room after finding out about the diary.
