Kissma no Yuutsu to Aitsu no Shisen

Average... the word that Tatsumi has been tormented with from his childhood all the way up to college, and he's developed an inferiority complex. In a desperate attempt to reinvent himself, he acts as a "compulsive kisser" ever since he got drunk. In a drinking party with his club, Kuga, one of the most popular guys there, catches Tatsumi's eyes. Noticing Kuga's glance, Tatsumi runs to the bathroom feeling strangely self-conscious, where he ends up coming face to face with Kuga. Tatsumi wants to avoid the awkward tension and makes for the door, but Kuga stops him. "Why am I the only person you don't kiss?"
