Solei's Big Problem featured in the male player character S support, about her fainting when she sees cute girls on the battlefield or whatever, is always something that gets brought up but I've yet to see anyone point out how totally off the rails ridiculous that whole thing is to begin with.
It's just... I dunno, dumb shallow writing, it's not consistent with her confident character and the fact she can be seen flirting with cute girls just fine in other support conversations, and feels like an episode of your average everyday romcom anime. It's stuff like this that makes me realize where all the FE fans who hate the new games are coming from.
