I totally get Fuko and BrownStorm. This chapter now... I know, this sounds crazy coming from an isekai fanboy, but this is just blend, brainless wishfullfillment. I want to sympathize with MC, but I can't if his behavior is too alien. And saying, that the setting is in a classic-era style fantasy world, so polygamy is fine, doesn't help. Still too alien. Some things just rubbed me the wrong way.
1. "Oh, you like that other girl. Okay, fuck her or even better get into a relationship with her to, even though you are already in one with me. It's fine, as I like her, too. Teehee." Yeah. No need for a girl that likes me just so much, that she is fine with sharing me. But it seems more like the author forced liberal bimbo girl logic onto the girls. Is this an 80's porn?
2. He's a prick. Normally this wouldn't fly without hurting someone.
3. Reverse the genders and you have a shitstorm.
But somehow his "No, we can't." in the end was the most infuriating thing. He went, starts cheating, because he knows Tetra would be cool with it, but wants to uphold morals at that point? I just want to punch him. Either live in a monogamous way or embrace the polygamous one, but don't milk it, you dumbf*ck!
