So I'm looking for this novel that had an interesting premise. If I remember correctly, MC transmigrates into a novel in which the genre is BL. She transmigrated as the wife of a war god(?) who is the original male lead of the world. In the original novel, she is a villainess or side character that gets killed in the future with her daughter. She decides to divorce the male lead and run away with her daughter. I think this had a promo, but I can't find it anymore, so that means the chapter was either deleted or I don't have the right name. I'd appreciate it if someone could help.
Okay, so JUST as I posted this, I decided to look in my MD List to see if I could find the promo through my hundreds of webcomics. ...and I found it. So I got one part wrong, it's not a BL genre, the FL is a crossdressing knight. And the divorce doesn't really happen cuz when the MC asks for the divorce, the ML crushes the table. If anyone's interested, the title's I Took My Warmonger Husband's Child. And there's currently no novel translation for it.
