Brother Invasion!
Mutsumi finds a hidden treasure map in the History Club room and invites everyone to go treasure hunting. Igarashi, Nanashima, Shinomiya and Nishina are less than thrilled about the idea, but after finding out Kae would be going alone with Mutsumi, they decide to go too. The four of them are confused by Mutsumi, because he treats Kae now the same way he always had. And so, they decide to ask him how he really feels.

Kiss Him, Not Me
Kae Serinuma is what you'd call a "fujoshi." When she sees boys getting along with each other, she loves to indulge in wild fantasies! One day her favorite anime character dies and the shock causes her to lose a ton of weight. Then four hot guys at school ask her out, but that isn't exciting to her at all — she'd rather see them date each other!
