Seo Jeongha, a fourth-year university student, decides to sell the speaker her ex-boyfriend gave her. The reason is simple: now that she has a handsome and sweet new crush, Park Minjun, that speaker has become a nuisance.

But when Seo Jeongha goes to complete the secondhand sale feeling relieved, the person who shows up to buy it is… her ex-boyfriend, Choi Seohun.

“You’re selling this for only 180,000 won when it cost way more than that?!”
