Anno is also a slut written by Savin and people love her. I don't think people hate her because she is a slut. Personally i think it's genuinely because her ntr scenes are written from a "cuck's perspective", without chance to intervene. Like your character enjoys watching her get fucked, no matter your actual opinion (feel free to call me out if its bullshit).
Tbf I haven't seen her scenes since a millenia ago as I tend to bench her quick cause I genuinely don't like to watch her scenes past her first ones.
My other issue is that they write her like both the "main bitch" and "town bycicle" (personally I had the same problem with Anno's writing), but I understand that's more of a personal issue than a general consensus. This is regardless of any ntr content. As someone who actually had sex with two of those when I was really young, it's really not something that interests me, cause I just felt disgusting after doing it.
My favourite character in TiTs is Fisianna, so that should tell you all you need to know on why I have these opinions.
