i think its cuz she s under the impression that ain isnt evil yet while she literally saw his dad have a body in a bag dragged after him so maybe she just thinks she cant change him once he s that way but she might be able to prevent ain from becoming like his dad .... tho she s probably wrong cuz that kid doesnt have an innocent bone in his body ╮( ̄▽ ̄)╭

This one page is basically the reason. I am not good with making summary’s so I just put it here.( ̄∇ ̄")
Take a shot everytime she says Ain.
Okay but on a serious note, I'm kinda confused. She wants to stop Ain from becoming the villain so she's like "I'm gonna shower him with love yadda yadda" but why is she so hostile to the duke?? Is her version of changing the story only for Ain?? I'm not hating I just truly don't remember and don't wanna reread.
