Due to his phobia of women, Inhwee has never dated anyone in his life, despite lying about being a "relationship expert" to everyone at school. So when Jeongwon comes to him and asks for "kissing lessons," Inhwee reluctantly agrees. But why do Jeongwon's "lessons" keep getting more specific and intimate? And why does Inhwee find himself actually aroused? While Inhwee spends more time with Jeongwon trying to figure all of this out, he is terrified his friends might get suspicious. As long as he keeps up his macho act, no one is going to catch on... right?
