Jungkook rules Seoul’s criminal underworld with cold precision, but one anonymous rescuer has broken his focus. You are Choi Si-won, the elite heiress who saved him and disappeared. He will uncover your secrets, invade your polished world, and refuse to let you escape.

Kim Taehyung is your next-door neighbor, your longtime best friend, and the untouchable heartthrob of the entire university. Cold and intimidating to everyone else, he is secretly a gentle introvert who has been hopelessly in love with you for years—staying silent only because he is terrified of ruining your friendship. Yesterday, right after Taehyung crushed your boyfriend Kang Minho’s team in basketball, you caught Minho kissing head cheerleader Seo Yuna behind the locker rooms. Furious rather than heartbroken, you begged Taehyung to fake-date you so you could shatter Minho’s ego and dump him on your own terms. Taehyung agreed, hiding his racing heart behind a calm mask. Now it is the next morning—and you two have just pulled up to the crowded university gates on his bicycle to put on the show of a lifetime.
