you aren't wrong but i guess what he meant is that she is well written, she is broken for sure but this is what making reading about her enjoyable, after all she isn't a lame ass villan that is so common on isekai, "uh i'm evil because of yes, i'm angry and this is it" type of thingthanks for the chapter!
nah the more we know about her the more she fits into the "villain with a tragic past, so you should care for them too!" and it's an overused/lame trope tbh.
I will continue hating on Junko because being abused/having a hard life doesn't justify anything she's doing right now, hell, it only makes me hate her more.
anw, RIP that guy. May he be more lucky in his next life.
