Ahn So-hee goes missing for a year, leaving Kang Ji-goo and the newly approved TV program behind.

The trio tries to live sober in the mountains with clean air and fresh vegetables, struggling against the emptiness of quitting alcohol.

The friends return to the city broke; Ji-goo starts food delivery and Ji-yeon works as a yoga instructor while So-hee returns to work feeling out of date.

Life in the city proves tough as the trio struggles to cope with heavy emotions and workplace shifts.

The friends spend time drinking and talking about their mothers at a Jeju Island restaurant

Ji-goo crashes her bike into an expensive luxury car, and Ji-yeon reveals a secret stash of booze left by her late mother to help pay the debt.

Ji-goo joins Mr. Kind Paper for volunteer work, and So-hee suddenly feels a strong attraction to Book-goo.

Ji-goo takes on what she thinks is a quick babysitting job. However, the baby's mother doesn't return as the day turns to night. She is left to take care of the baby with So-hee and Ji-yeon and ends up suffering throughout the night. Can they stop the baby from crying and find its mother?

So-hee gets ready to visit her mother in Gwangju on her day off, and Book-goo accompanies her for the first time. However, strangely, he seems all too familiar with her place. Seon-jung and Sun-guk are arguing about Sun-guk's birthday dinner with their parents, and Ji-yeon pokes her nose into it to solve the problem. Meanwhile, Ji-goo is worried about Ji-yeon as she cannot get in touch with her.

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.
