A girl who has never been in a real relationship and a love expert named Neptune, who is a mysterious business boss of the gang, she is a sad and pitiful person who is protected by others. He is a master of love and approaches his prey like a hunter. The prey is as stupid as a stupid rabbit. The hunter is cruel and ruthless. He will not let any woman stop. Silly Rabbit is so stupid that he only knows how to be kind to his prey without asking for anything in return. The hunter just wants to attack her but does not want to be moved by her pure kindness. But after learning about her tragic story of a sad backflow, the hunter transformed into an old fox and taught the newly walking little fox how to identify a scumbag: I lied to you again and again just to teach you not to be deceived by other bad men. The second time, my way of protecting you has come to an end, and you have to walk your own way in life.
