That haremette affairs talk was kind of interesting. They don't really view each other as rivals competing for a monopoly on Takahiro's attention and affection, but more like supporting and encouraging each other to get a piece of him.
Gerbera's gonna need to be creative, maybe some... bondage on herself might help her seal the deal with him. As for Rose... well, considering how much she's advanced in the face department, I suppose she, uh, upgraded herself in
certain places too if she intends to do the deed like the other haremettes. Hopefully no wood splinters are in store for Takahiro when the time comes.
