Ahn So-hee disappears without a trace, leaving Kang Ji-goo with their TV program that just got approved to air. One year later, she still hasn't returned. Distressed and tormented, Director Kang can't wait any longer and goes out to find her.

The three girls enjoy living green in the mountain, surrounded by clean air and fresh vegetables, but they feel empty inside ever since they quit drinking alcohol. At night, they return from their self-build composting toilet together, and Ji-goo sees a girl in a white dress in the woods.

The girls are back in the city, but they are completely broke. Ji-goo starts going on deliveries to earn living expenses, and Ji-yeon gets a job as a yoga instructor. Meanwhile, So-hee has a hard time filling in the two years career gap. She feels lost as she has a lot to catch up on after returning to the media industry.

Ji-yeon's day gets filled with events reminding her of her mom when she was a little child. Today the girls miss their moms, so they gather to have a drink. As they enjoy the dishes of Jeju Island, So-hee and Ji-goo realize it's the death anniversary of Ji-yeon's mother. As the drinks go down, they spew out their issues with their moms.

Ji-goo gets into an accident while going for deliveries on her bike. Fortunately, she is not badly injured, but the car she ran into was a luxury car, and she has to pay for the damage. When Ji-goo and So-hee are in despair, Ji-yeon brings them to a liquor storage that her late mother left for her.

Ji-goo runs into Mr. Kind Paper and ends up following him to his volunteer work at a polytechnic school, and Ji-yeon makes a bet with Seon-jung for a wish. Meanwhile, So-he and Book-goo have a meeting for their show just like any other day, and suddenly, So-hee feels extremely attracted to Book-goo, and she cannot stay focused on her work.

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.
