Ehhh I guess I mean both if we're talking realistically speaking are both pretty traumatic you have this story where her entire family gets killed not told why they were she gets locked in a place and then branded by hot metal probably also forced to bed him, also i dont know if they have stated yet but did they have a child together (if they did probably killed in front of mc or maybe done out of site) and theres probably more traumatic stuff that happened that hasnt been stated yet. The yaoi version is just as bad the father dies he can't go to his funeral never gets to say bye his bestfriend growing up I belive dies child killed by the ml, one or both legs broken, forced to follow ml through thr battlefield and spend every night in bed with ml, then dies only because ml wanted to see how worried he got for him if he was seriously hurt bit didn't realize the mc would take on the injuries to save him.
Both also go into a shock like state when they hear or see anything to do with they used to love. The only slight difference between the straight and yaoi versions is that usually the straights tend to pick not to go back to the shitty ml but there is still plenty that do, yaoi on the other hand tend to stay more with the ml but you have a few that don't.
But none the less if you prefer the straight couples more then that's you everyone has there line they don't like to cross. I personally love all versions (that sounds horrid I know lol) watching characters mind break and seeing what actions and how they push past it or handle it is simply an intoxicating drug for me
Don’t forget that the reason why yaoi may have worse topics is because rape is very normalized in the red flag stories. To the point that seeing it makes people desensitized to it. Compared to straight stories where people would be in shock since a lot of times straight stories wouldn’t have the rape theme. There’s some straight stories that do have it, but not as often
So this seems like a straight version of another story I read that was yaoi there's only slight differences like for instances this one has a straight couple where as the other was a yaoi and this one also seems like the ml might change where as the other one the ml did not change. This one its family problem that she wasn't made aware of where as the yaoi it was a culture difference that was not told to, to the mc.
