Friend Graduation

Kang Min-jae sees ghosts. His ancestral grandfather spirit has a youngest son who died long ago, and as fate would have it, he looks exactly like Jung Ju-haeng, the top student in school. While trying to look after Ju-haeng because of his grandfather, Min-jae led Ju-haeng to misunderstand that he liked him—but at some point, those feelings became real. Now, he must deceive his grandfather, who views Ju-haeng as equal to his own youngest son, while simultaneously pretending to be just a friend to win Ju-haeng's heart.
