Review Detail of Bisaster in I Got Reincarnated into R18 Mecha Novels as a Side Characters

Could be worse, could be better. The scope of the setting feels way too big to me but that's not a given yet. There's a lot of info dumpy stuff that I care very little about but mecha fans might enjoy the technobabble, The fact that he barely read the setting he incarnated in makes the the premise kinda meh and fails to scratch that itch that this genre would usually satisfy. I feel like it's a middle ground where nobody will feel satisfied. The biggest issue this has is the characters, so far there's not one character that's actually likeable. The MC is super submissive to the women so far, very little self respect present in him. Feels like he continued being a side character even after the memories got unlocked. A more proactive side character but one nonetheless. Smells very Japanese MC so far. The main heroine so far is feels like a generic chinese cold beauty with no redeeming feature beyond said beauty. The usual stupid cliche of the MC being sometime afraid of her obviously has to happen. The mc feels like her lapdog now that I think about it, literally has to ask permission to go out at night and he gets warned not to ruin the family name. The guy is then happy he's allowed to go walkies, it's kinda hilarious but also sad. The fact that he's trying to make the marriage work with such a character just makes it sad in general. The maid/second heroine is the worst offender, she's actively antagonistic for no real reason and the MC just keeps accepting the abuse. Please note that the MC has the memories of his body and even with an outsiders perspective can't tell what her issues her. Her role so far was to verbally abuse the MC in every interaction they have while the Japanese MC keeps wondering what he did wrong and how he can make it up to her. The rest of the characters either have other issues that make them meh, like the mother withholding arguably valuable information for a happier married life, or didn't get enough screen time yet beyond a scene or two.
