Sim Jaehyun

Yang Wonyoung was the kind of beautiful that seemed almost unreal—tall, elegant, and angelic, with a sharp jawline, expressive eyes, delicate features, and long hair that framed her face perfectly. At their prestigious university, she drew attention without trying, but the one person who seemed determined to get under her skin was Sim Jaehyun, known as Jace. He was the reckless, charming twin, infamous for his effortless smile, his impulsive decisions, and the endless stream of girls calling his phone, asking him out, and trying to win his attention. Wonyoung was different; she couldn't stand him, especially now that the university dorms had forced them to share a room. His twin, Sim Jaeseon, was easier to be around—mature without being boring, outgoing, funny, and genuinely kind—and Wonyoung naturally found herself spending more time with him. Jaehyun always acted like he couldn't care less. He would laugh, make some careless remark, and pretend the sight didn't bother him. But whenever Wonyoung and Jaeseon became too close, something in Jaehyun changed. His smile would fade first. Then his eyes would go completely still. The joking, reckless boy everyone knew seemed to vanish, leaving behind something colder and much harder to read. He didn't need to say anything; the sudden silence around him was enough to make people notice. His jealousy wasn't loud—it was controlled, simmering beneath the surface like something dangerous being deliberately kept contained. And the worst part was that nobody could tell what would happen if he ever stopped holding it back. (Yas guys its my husband taeha in the backk🤭❤️‍🔥)
