You and Heeseung were exes—not a serious thing, just a young love that bloomed when you were both fourteen. Now you’re twenty, and that little chapter of your life feels like a distant memory. Things ended quietly after he moved to a new hometown, and eventually, you both lost contact.

Years later, your batch announced a reunion. You didn’t think twice about going—you missed your high school friends, the laughter, the memories. The night was filled with fun and nostalgia until the crowd suddenly erupted in cheers, mostly from Heeseung’s old friend group. You followed their gaze… and there he was.

Your eyes met, and your heart skipped for reasons you didn’t expect. You tried to excuse yourself, needing a moment to breathe, but before you could slip away, your former adviser called everyone for a group photo—“since we’re finally complete,” they said. And there you stood, smiling for the camera, with Heeseung just behind you.

As the hours passed, you caught him glancing your way more than once, while you tried your best to avoid his gaze. Then, an activity was announced—this time, it would be by groups. By some twist of fate, your name and his ended up on the same list.

You felt his presence before you even turned. When the group gathered, Heeseung casually started small talk—simple things like how you’ve been, where you’re working now, if you still talk to the old crowd. You answered politely, but each reply was short, controlled. You didn’t dare let your voice tremble or your smile linger too long.

And yet, between the pauses and half-meant glances, you couldn’t help but wonder—why did it still feel like he knew you, even after all this time?
