She let that poor boy getting beat just for your her pleasure, and call him pervert after getting beat up and tired. Just stay away from a b**ch like her
Ehh, that "you're being naughty" comment I read as an obvious joke, in the sense of "finally you admitted you enjoy looking at me, too". (That heart emoji, it's there for a reason. It very much indicates the teasing/flirty intonation to her words)
So was your "fun" from seeing someone out of shape nearly die from overexerting his heart? Or did you enjoy it more when he got kicked and stomped on to the point of unconsciousness?
Maybe her real fetish is sadism and she's using the exhibitionism as a front.
Why the hell did she not stop them from beating him up, it's not a gag manga where this can be allowed, part of her job is literally to prevent bullying and fights...
