My Perfect Senior's Secret

Taehyeok is the perfect upperclassman: kind to everyone, effortlessly charming, and at the top of his department.

The only person who knows his true self is his underclassman, Moeum, 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.
