He used to drive her insane. Always teasing, always provoking, always acting like he had the upper hand. But she never stayed quiet. She gave it right back, and somewhere in the fire of their constant battles, she fell for him. And just when everything started to feel real, he disappeared. No warning. No explanation. Just silence. She tried to hate him. I tried to forget. But the questions never stopped haunting her. Why did he leave? Did any of it mean anything to him? Five years passed. She built walls. Moved on. Or at least, she thought she did. Then he came back. Older. Quieter. Still carrying secrets she didn't understand. He told her about his mother. About the pain. And for a moment, despite everything, she let herself care. But the truth is, she still hasn't forgiven him. And she's not sure if she ever will.

Eunjin's life motto is simple: Avoid drama. Avoid cameras. Avoid making a fool of yourself in public. So naturally, she spills an entire iced coffee on Lee Heeseung-K-pop royalty, heartthrob of millions, and the human version of a Calvin Klein ad. What was supposed to be a caffeine run turns into a headline-worthy disaster, a viral photo, and an accidental friendship with the hottest idol in Seoul. But Heeseung? He's spiraling. Into her. And his group chat is in shambles because of it. As texts get bolder, dates get sneakier, and chaos gets messier, Heeseung has one problem: He's falling in love. Like, full-speed, no-brakes, fan-cams-could-never type of love. Can a superstar and a civilian survive spilled coffee, stalking paparazzi, and the most unhinged idol group chat in K-pop history? Fake innocence. Real feelings. And one very public accident no one can unsend.
