Ji-yeon and Ji-goo always got into fights. But this time, it looks serious. So-hee has a hard time between the two, trying to calm things down. Later, Ji-yeon shows up with her blind date in front of Ji-goo and her male friend, and it gets interesting.

Seon-yeong lets Ji-yeon stay at her place as she has nowhere else to go, but there is a strict rule in her house. Since Sun-guk suffers from hyperacusis, no one is allowed to make even the slightest sound. Will Ji-yeon be able to get through it without breaking the unbelievable rule?

So-hee realizes that she genuinely likes Book-goo and gives in to her feelings and dreams of a future with him. However, at that moment, an unexpected person appears before them. Meanwhile, Woo-ju asks Ji-goo if she would join him overseas to help pursue his artwork, and Ji-yeon tries her best to mend Director Kim and Sun-guk's relationship.
