Yeah. What
@Hurgh wrote. It suffers from a bad case of OHD (Overblown Harem Disease). The other girls could also be identified as some sort of gyaru and that would give the story some sort of spin, as we actually might be red-herringed by the obvious FML. But this doesn't seem to be the case, as this story is seemingly going nowhere. The pace is bad and looks too random, as if the author lost interest in the main story. (It might be a good step too completely turn away from a concept if you notice some better direction, but this doesn't seem to be happening here.)
Also I somehow dislike the MC.
(We are now at chapter 21.)
