I mean, is she just completely surrounded by people as screwed up as she is? LOL. Yuuki seems nice enough, until she literally murdered her childhood friend in cold blood, ostensibly because she didn't sleep with her?
The harem shenanigans and her facial expressions are hilarious, but it seems very unlikely that any of the harem members (nor the MC herself) will actually be in any way sympathetic characters that we want to see their romance bloom for. I'm still here for this anyway though.
