One evening in the office, Matsuda finds out his girlfriend has cheated on him, severely wounding his pride. But when Katou sees his frustration, he says the unexpected. "You have bad taste, obsessing over these boring women. You should choose me"... And the very next moment, Matsuda finds Katou's lips meeting his own! (Source: Taiyo Tosho)
