Lee Heeseung

Title: “Color Theory” Lee Heeseung was the kind of boy who made people forget what they were about to say. Effortlessly sharp, devastatingly composed, and dangerously aware of every room he walked into. He was the type of person who didn't need to try and somehow still won everything. Girls wanted his attention. Guys wanted his approval. Teachers let things slide because even they weren't immune to that face, that posture, that quiet authority he carried like it was sewn into him. Y/N was the only one who never flinched. That was the problem. That had always been the problem. Her beauty was the kind that made guys look twice and wish for more—soft features, a radiant smile, and eyes that sparkled with mischief. Her presence radiated a subtle confidence, drawing people in and making her stand apart even in a crowded room. Her rivalry with Heeseung was the stuff of school legend—cold, elegant, and relentless. They competed for everything and conceded nothing. But somewhere between the sharp looks and sharper words, something else had taken root in Heeseung. Something possessive. Something that had no name but showed up every time someone else dared to make a move on what he had spent years quietly claiming as his. He never said anything. He never had to. He just appeared—beside her at parties, at the edge of conversations she was having with other people, close enough to make a point without ever making it out loud. Then came the party. He told her to wear red—flat, certain, like it wasn't even a request. She almost pushed back. Instead, she wore it, telling herself it meant nothing. The color was flattering on her—all colors were—but the meaning behind it remained hidden. What she didn't know was that it was a traffic light party. Red meant taken. And Heeseung had known that from the very start. But when she found out, she changed to green. The rules broke that night—her choice, her move. And for once, he was the one left on the outside looking in.
