When Haru is leered at by the others at a drinking party, a freshman named Leo—who is very popular with the ladies—steps in to save him. Haru drunkenly confides in Leo, but unintentionally teases him in the process. It's then that Leo asks, "What are you doing in this club if you're not having sex?" Before pushing him down and kissing him!
