Can only agree with those saying it'd be hilarious if all vampires were like Ruruna and it turns out the support group is just all of them completely baffled by everything humans are doing.
Shocked she acknowledges she messed up their lives lol
I was surprised by this as well. Not just because it feels more self-aware than Ruruna typically is, but also because I'm not even sure I'd say it's true (yet), kinda from a "technical standpoint". I mean they continue at school as normal, right? Still got their social circles and all; no indication their grades or teach's job or anything are suffering. There's really no indication their lives got worse, I think.
Now, "mess with", that'd be different. That I'd agree with.
