Merry Mary

In a musical theater filled with excitement, Mary jumped up from her seat and sang loudly. She is dragged out of the theater by the staff. Dae Gu, sitting on the top seat, gives a telescope to his girlfriend, who complains she can't see well. Sung Ja, Mary's mother, gets angry because the 120 dollars she saved disappeared. Then she finds a musical ticket in Mary's pocket when she comes home. Hungry Mary runs away from her mother and sees an advertising poster in front of the convenience store.

Mary beats Dae Gu like crazy, and Dae Gu grabs her arms, claiming that he didn't hear it on purpose. Mary throws a t-shirt she got from her ex-boyfriend into a recycling bin and leaves. Dae Gu looks at the recycling bin after finishing his black bean noodles. Mary lays as if she is dead in her room with a suicide note. She gets up when Sung Ja calls her for dinner. Mary goes to the department store with her coupons to get samples. On her way back home, she encounters Bi Dan and her gang.

Mary, who got a job at Emperor Market, spends her time practicing greetings alone and dozing off. Dae Gu looks at her as pathetic. Daegu only finds things that she doesn't have at the store. Mary tells him to leave immediately before reporting him, but Dae Gu keeps interrupting her work. After So Ran buys clothes at Eun Ja's shop, she continues to go on blind dates. Mary is surprised to learn that Bi Dan, whom she encountered last time, is Hwang Jae's daughter.

Surprised by Mary and Dae Gu's ambush kiss, the people at the TMH take pictures. Dae Gu is happy to get his membership fee back. Mary pushes Eun Ja, who wants to get the money instead, and takes the money. The three of them sit in front of the same grill and begin to grill meat. Mary is upset because Dae Gu eats meat so fast. After the meetup, Mary asks Dae Gu if he will go home even though they kissed today and suggests going to a sauna to play a card game betting on 30 dollars each.

Mary pretends she doesn't know Dae Gu, and Dae Gu tries to say about the kiss at the restaurant. Mary, who is embarrassed, rushes Do Jin to go. Dae Gu worries he might be kicked out if Mary and Do Jin are in a relationship, so he starts practicing saying he likes Mary in front of the mirror. After watching the movie, Mary and Do Jin see a car blocking in front of their car. They wait for the owner of the car. When So Ran returns with lots of shopping bags, they scold her.

After the fashion show, Dae Gu leaves dressed in a suit and walks pleasantly by the gaze of people. When So Ran asks for Dae Gu's contact information, Mary asks why she wants it. So Ran asks Mary if she likes him. Mary denies it and gives Dae Gu's address to So Ran. So Ran plans to go to Dae Gu directly but changes her mind because she needs a good strategy. While working part-time as a backing vocalist, Mary wonders what Dae Gu and So Ran might do when they meet.
