Kang Jiwon is 22, fresh out of college, working at a café in Seoul while trying to figure out what adulthood expects from her. Her nights are loud, chaotic, and filled with games and friends-until her neighbor starts complaining. Jay is sarcastic, persistent, and far too present in her life to be just a stranger. What begins as constant bickering slowly turns into comfort, late-night conversations, and feelings neither of them planned for. But when love arrives alongside fear, Jiwon starts pulling away-afraid of what the future might hold. Jay, however, refuses to leave. Will Jiwon push him away or let him stay?

They've been enemies since childhood ever since he broke her priceless porcelain doll. Now Seoul's most notorious chaebol rivals, Park Jong-seong and Kang Ji-yu, are forced into an arranged marriage to protect their families' empire. He calls her chaos. She calls him destruction. Between revenge pranks, explosive arguments, and elite society watching their every move, this marriage is anything but peaceful. Can two lifelong enemies survive being married or will they destroy each other first?
