Kyungsoo is an assumed trollop. In other words, he's a fake . Everybody thinks he slept with about everyone who said they did it with him but all of it is for show. It's something about helping the losers in their school that had him agreeing to this set up. However, his dirty reputation makes him Wu Yifan and his band of cohort's target for bullying. Kyungsoo struggles with his double reputation: the trollop and the bullied.
