When Sehun gets accepted as an intern at one of the most prestigious and dangerous mental hospitals in all of South Korea, he unknowingly gets in over his head as one of the patients takes an unhealthy interest in him and refuses to get out of his head. But Sehun has always liked a good equation, and Kim Jongin poses to be an addicting one.

"You don't seem to understand, Sehun."

He said, and there was something in his voice that compelled Sehun to listen. Some sort of warning that what he'd say next would be essential to how things would play out in the future. Some sort of foreboding that made Sehun freeze in his seat as Jongin leaned closer, almost smug.

"I might be the one charge with being crazy, but honey...you're still the one who continues to seek me out."

A wicked smile.

"What does that say about you?"
