It's generic. The title is really boring.
It was incredibly hard for me to read past the initial *holy hell it's super generic* phase, but after that, it becomes less generic (but still generic), which made it readable. Rather, a future character embodies the "strong boy harem" trope, in order to be a foil for the MC. While it's "technically" a harem, since MC really only has female companions, it's not actually a "harem" because there is no romantic tension. Well, except for one, which I can accept.
Simply put. It uses the door in the face strategy to me. It's so cringe-ly boring at the beginning with how "forced" the events feel, but after that initial phase it becomes "decent" enough for me to actually enjoy myself to some extent.
