Oh, I was hoping for a simple romance between 2 characters, but sure why not. By the end he'll be pestered by at least 5 women and have a bed of thighs (and possibly a pillow of beasts and blanket of... something (Iegimately don't know what could work as a blanket)). He'll sleep blissfully surrounded by his harem (probably). That or he'll never get to sleep again.
I get the feeling that Chita was the one with him in his flashback. At least I hope so. I'm already sad enough that I already like her more than the FL even though she'll most certainly lose.
I’m fine with more girls being added, just as long as there are no male love rivals. This isn’t an isekai so I assume it won’t be a harem since it goes against taboo, but I hope it does, because I wouldn’t want anyone to feel left out.
