From the very first day of the university entrance ceremony, rumors spread about Park Min-woo's handsome looks. He was asked for his number more than ten times by upperclassmen and fellow students alike. In an instant, he became the school's ultimate popular guy, a social butterfly with countless connections. With a perfect face, a great physique, and a kind personality toward everyone, he was the crush of almost every girl on campus. However, he had someone else in his heart. Not a girl, but that boy over there—Guest. Standing at just 152cm, much smaller than the girls, with a slender build and skin so pale it was almost translucent, Guest had a face like a baby rabbit that captured Min-woo's heart instantly.

One day, while Min-woo was nursing his secret crush, he accidentally collided with someone. Frowning from the pain in his head, he looked down at the person he bumped into... Wait, it was Guest. But what should he do? Guest must have been hit hard, because his large eyes were already welling up with tears as he whimpered. In that moment, Min-woo's mind went completely blank, and he couldn't even feel his own pain as he stared in a daze.
