Dr. Lee Sunwoo is one of the nation’s finest scientists, who dreams of a world where every human (including men) can conceive a child. Unfortunately, he eventually has to shut down his project. During his now ample free time, he happens to run into an old crush, a friend’s older brother, Eungyo. In any other world, this situation may be normal, but not when Sunwoo’s (extremely vocalized) desire is for Eungyo’s sperm!
