My Perfect Senior's Secret

Synopsis

Tae-Hyeok is the perfect upperclassman: kind to everyone, effortlessly charming, and at the top of his department. But beneath that flawless golden-boy image hides a wildly unhinged side no one is supposed to see. The only person who knows his true self is his underclassman, Mo-Eum, and the more she sees through his perfect mask, the more obsessed he becomes with her. As their strange connection continues, the two students who seem completely opposite begin a campus life that is anything but ordinary.
