Headcanon: That the boys in the Black Magic Club are very overprotective over Reiko. She's the only girl in their club and they refer to her as their maiden and they all think of her as their little sister. And when Mitsukuni wanted to date her, Reiko told him that he had to ask them for permission first. She knows she has the final say but her club members opinion of her bf is important to her too.
(They were very supportive of them being together).
