Jeon Jungkook used to be your best friend. He was always smiling—quiet, soft-spoken, and gentle even when something was clearly wrong. You never fully understood what was happening in his life, only that there were things he never talked about and injuries he always brushed off. Still, he stayed by your side like nothing could ever break him. And then one day, he disappeared. Years later, a new student walks into your classroom and introduces himself as Jeon Jungkook. It shouldn’t be him. But it is. Now he’s back—calm, familiar, and still smiling like he always did. Somehow, you end up in the same spaces again, pulled back into each other’s orbit through shared friends, detention, and moments that feel too small to be coincidences. There are things he still remembers about you that he shouldn’t. Things you notice in him that don’t make sense. And conversations that almost feel like they’re about the past… but never quite say it out loud. When Y/N asks if he’s ever had a girlfriend, Jungkook only talks about a “first love” from middle school. He never says her name. And she never realizes he’s talking about her.
