Dr. Lee Sun-Woo 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, Eun-Gyo. In any other world, this situation may be normal, but not when Sun-Woo's (extremely vocalized) desire is for Eun-Gyo's sperm!
