I'm a little confused I thought that the mom was jealous/ might have had a history with Weiss and Zieg not that it's oh you absolutely have to beat everyone and be the absolute best. She only asked about Lily since it was specifically Weiss and Ziegline's daughter.
"Oh no I want my characters perfect from the get go so that there's no story and no conflict and no character growth" What the hell are we doing? These situations are the lifeblood of stories because they allow characters to change and actually have to confront something about themselves in...
His mom is the worst wtf. Like if that happened naturally that would be fine but holy shit she hates seeing him succeed. AND THEY HAVE A DAUGHTER THAT IS WILLING TO TAKE OVER SHES JSUT BEING SEXIST!
I wanna say she's reincarnated but also probably met MC when they were younger. Or maybe like that one otome isekai where she lived a life in this world reincarnated into the modern day then regressed back to their first life.
