Highschool can be lonely. Kim Aerin, a timid and vulnerable girl, will do anything to avoid that lonely path, even if it means being in a toxic relationship.She met Sim Jaeyun, a guy from another school, who couldn't stand that weak side of her and wants to protect her. However, is that a sign of sympathy or love? Before he could admit everything, it was already too late. Feat.
