We Broke Up

Ji Won-young is an aspiring musician and the lead singer of a band while Noh Woo-ri is a college student. After meeting at one of Won-young's gigs, their relationship blossomed and they soon begin living together. Things become complicated when they decide to part ways but due to various problems with the security deposit and the loan on the apartment, they are forced to remain living together until the contract is up. Since the two are too rebellious towards each other, they end up formulating few rules for living which included not interfering in each other's life. However, Won-young's sudden suggestion of non interference in each other's love life, concerns Woo-ri and she becomes worried that Won-young already has plans of moving on soon after their break up. The same day Won-young discovers that the band's department no longer belongs to them and decides to work as a part-time in a store, there he happens to meet Yoon Ni-na, who later, on purpose takes Won-young's phone along while he is billing and leaves hers behind that was identical to his. Meanwhile, Woo-ri seems to be worried about Won-young not returning home at night and wonders if he has already started dating. The next day, she thinks a lot about calling him but tries to convince herself not to since they've already broken up. However, she ends up calling him, but when she discovers the phone to have been picked up by a woman, she immediately hangs up. She then receives a message for an interview and determines to get a job. On the other hand, Ni-na calls up Won-young and asks him to return her phone, who is at first reluctant to do so, but then agrees when offered 300 dollars. He then goes and discovers Ni-na to be a music director who offers him a job for his band The Band I Do Not Know. He asks his band members to arrive at once and they do so. They have a wonderful program that reassures Ni-na about their talent, and she pays them sufficiently. Woo-ri ends up at a library and meets a former classmate Seo Hyun-woo, while they both pick up the same book for the same interview, they study the whole night but Woo-ri ends up sleeping. Hyun-woo looks at her presentation and modifies it a bit to make it just perfect. The next day the two wake up in library late for the interview and rush to the office without changing. During her presentation, Woo-ri gets nervous on seeing a new presentation but boosts up on the very next slide. Both Hyun-woo and Woo-ri get selected for Gaha Entertainment at different positions.

The Band I Do Not Know members celebrate at home along with Ni-na and on the other hand, Woo-ri brings along Hyun-woo to celebrate their first day at job and after seeing the band celebrating, those two join them too.
