Adachi's popular with the ladies, and the fact he's a little dumb makes him even more charming. He's constantly bragging about his conquests. "I can pick up any girl I want!" Just when his ego's getting the better of him, someone challenges him to pick up a guy. Strangely excited at the prospect, Adachi begins to put the moves on his co-worker, Sera, who's rumored to be gay. Undeterred by his cold demeanor, Adachi instead finds himself imagining Sera writhing in pleasure at his advances. However, one day... "Wait, why am I on the bottom!? What is going on here!??" A battle of hearts between the calm-and-collected co-worker, and the former-nerd-turned-playboy!
