Can bl’s stop demonizing female characters

I agree but this one is different. The other females in this story are not demonetized. Also, she's not after the same, she's a lesbian. My guess is she's got internalized homophobia that she's going to project onto the uke. A big conflict is going to happen (like her outing him or spreading rumors) leading to the uke eventually proclaiming his feelings for seme.
Why tf did she marry a man
i don't think it's a problem you know.. people learn things everyday and that's how life should be... as long as masumi is happy i couldn't wish more.
well sometimes queer people are afraid to come out to their family and end up marrying someone they don't want to, I think you should try to look at her ending in that kind of perspective. I'm not gonna lie, I was pretty disappointed with her ending too, but what can I do about it lol.
also, she might just be bi idk
