"You're mine~"

At the most prestigious school in the city, perfection had a name, Choi San.

He was the golden standard-brilliant, breathtaking, and beloved. Students adored him, teachers respected him, and the hallways seemed to glow a little brighter when he walked through them. With a flawless career, a gorgeous fiancée, and a reputation as both a genius choreographer and a genuinely kind soul, San believed he was living the life he'd always dreamed of.

But perfection is fragile.

Late nights. Faint traces of unfamiliar cologne. Lipstick smeared in ways that didn't make sense. Doubt crept in quietly, settling in the corners of his once-certain heart.

And then, one ordinary afternoon, a new student stepped into his classroom-Kang Yeosang. Shy, soft-spoken, with gentle eyes that seemed too pure for the world around him, Yeosang's arrival felt small to everyone else.

To San, it felt like the beginning of something that would unravel everything he thought he knew about love, loyalty, and himself.
