I'm hyperfixating for this fanfic again atm so I have angst ideas/theories for Y/N's mom
Y/N doesn't know anything about his blood family, why? I think its because Y/N's mom definitely cut ties with them, but it was not her decision to make. When her family found out she got impregnated by a villain, they were disgusted, forcing her out of their home because she is now "corrupted". (Headcannon that her family was very Conservative and/or religious)
When Y/N was first born, his mom's postpartum depression was so bad that she nearly killed him on multiple occasions. I would think she tried abandoning him a few times but every time her motherly instincts just scream at her to hold and care for her baby.
I feel that Y/N's mom definitely loved him, if she had a choice she would have raised him and watch him grow up, but she's not capable of doing so because of all of her mental problems, financial struggles, and maybe she was tracked down too? (This was inspired by Mitski's I Bet On Losing Dogs, the "I always want you when I'm fine." lyric.)
