It's kinda confusing spoilers I guess
..
Okay first of she is the marchioness she was summoned by rothbarts father to be his swan yada yada yada rothbarts father wants fl to go back to her world so his son rothbart would feel the pain of losing the one he loves (the amount of times I've read a story were a character is punished just bcs they were born) so fast forward she returns to be with her dying mom on earth and doesn't remember anything when she was in the other world
So here's the thing I'm not sure how old the ml is but when fl was transported to the other world she was in middle school and in like a few months got pregnant and gave birth...... So uhh yeah....
So yeah that's basically why the ml wanted to punish her
Thanks for the clarification. Thought it was something dumb like she think he will eventually not love her and thats why she abandon her husband and son, which then what lead to them being villains. Probably save my sanity and skip this one if she wasnt at fault for leaving them.
Couldn't stomach the assault so I skip to the last few chapters, so did she created this mess herself? I might give this another chance if it is about facing the villian you created and its consequences.
