Y/N learned early on that you can't be liked by everyone.
But if there's one person who truly can't stand her - and the feeling is entirely mutual - it's Sim Jaeyun.
He's the perfect student: kind, brilliant, effortlessly charming.
Except when she's around.
With Y/N, he turns sharp, competitive, and frustratingly calm.
And she never misses a chance to show him just how insufferable she thinks he is.
But when a series of coincidences forces them to spend more time together, everything starts to shift.
Between sarcastic remarks, loaded silences, and wounded pride, what once felt like rivalry begins to turn into something far more complicated - and dangerously real.
Because hate is a thin line.
And sometimes, it only takes one step to cross it.
