Your and My Secret  Vol. 1,2,3,4,6,7  (Manga) ( 6 Books) 
Akira notices a change in his feeling towards Senbongi and is freaking out. Just because he's in a girl's body doesn't mean he should like a guy! He's a guy at heart! But on the last night of the school trip, the girls are on a rendezvous to the guys' room. There, Akira gets jealous when other girls are touching and snapping photos with Senbongi. When the girls start asking Senbongi out, Akira, without knowing what he's doing, reaches out and declares Senbongi's his. Does this mean that they're now a couple?
