Ahn Sunghyun is a university student who's lived his life hiding his true identity as a gay man. When he plans to meet up with an acquaintance from a gay dating app, he runs away when he finds out that said acquaintance is a college classmate who is trying to out him, only to end up in a car accident in the process. Thinking his life was over just like that, he gets a surprise when he finds that he's now possessing the body of character "Han Sunghyun", the villain from a novel he read in his past life.
However, there's just one problem: Han Sunghyun is someone living on borrowed time. Feeling that the current circumstances are unfair, Sunghyun thinks, 'Well, if I'm going to die anyway, shouldn't I live out the dream of being a rich unemployed person for a while?' He promises himself that he'll try everything he wants to do with the remaining time he has.
Shouldn't you have sex at least once before you die. That's what Sunghyun thought, so he musters up the courage to go to a gay bar in order to find a one night stand, only to get involved with a man he should've never gotten involved with.
"J-Jo-Joo Jaeyoung-ssi."
"Yes, this is Joo Jaeyoung you're speaking with."
How will Sunghyun's time-limited life turn out after spending the night with Joo Jaeyoung, the second male lead in the novel who hates Han Sunghyun?
