Reiko is such a treasure. But if they're that aware of the tropes of that world, and otome games, they should realize Reiko is pretty much a stock heroine at this point.
@Tersione paradoxically, there is a subset of really, really hot nice girls who guys don't approach because they're intimidated by them - and the first guy to give them some attention melts them. That's how you see them sometimes end up with "normal" guys and you wonder how.
@Rhiene their marriage is such a sham, and he hates her so much, that if he were provided with proof that she's as pure as the driven snow, he'd claim it was magic or that she slept with whoever it took to fake the proof.
@kawaiidesune I'm not sure if Iroha classifies as childhood friend or not, but she's arguably holding an even worse card: the hot chick who attacks relentlessly.
That being said, she has the title girl and first girl cards, and those are EXTREMELY powerful.
For those wondering about the MC's thoughts on his power level: he believes he's genuinely a level 2, but thinks he has some hax skill that lets him play with barriers.
