@Almaz_Hiro as it is going right now your fears might become true. He is starting to realize that she is indeed a girl. This whole setup is going to be romance without developement until axed or dropped.
@Ihcky Your probably right. I'll see how this first volume ends. And decide to follow or drop at that point. Holding out hope that title refers to himari's new life and not her living situation with her brother.
