Fake’s mom if she was still alive and met Demon Waifu-
She would just be like, " Aw..! [ Insert Fake’s actual name ] You have a girlfriend?- "
And she would like be so nice and bubbly to her lol
Demon waifu would probably be on her best behavior since she doesnt like it when she embarrasses Fake- unless it is anyone not in his family other than Sage
