Lee Areum and Park Sunghoon have been rivals, neighbors, and something in between for as long as they can remember. Competing in grades, bickering over the smallest things, and pushing each other's buttons-it was just how they worked. No matter how much they fought, they always found their way back to each other.
Until one day, they didn't.
A crack in their trust shattered everything, leaving them nothing but painful silence.
Years later, fate plays its cruel game, forcing them to cross paths once more. Sunghoon, the boy who once filled her world with endless arguments and unspoken comfort, now stands before her like a stranger wearing a familiar face.
The memories rush back. The emotions hit harder. But one question lingers-after all this time, is he still the boy she once knew?
Or just the boy that she met before?
