Yup that's how it goes down, MC always get'n attack by some snappy girls who always jump the gun before he could give a reasonable answer to why he's there, and what he's doing there.

At least if I'm correct, she is not the usual cliche "you've seen me naked, now you need to die" fairy girl stereotype

If I guess correctly her identity from novel (kind of 50-50 on this one, novel and animation follow completely different path) she is highborn naive girl who is one of 7 lights (or better, she was scammed to become one because of her identity and gullibility) and wants to avenge the defeated members because she's been told all the lies how Wang Hao extorted students, beaten 7 lights members when they tried to prevent that and protect students and then robbed and humiliated them. In novel she is clueless about everything and believes 7 lights are the good guys of the academy even though they murdered her best friend when she tried exposing their scam. She actually believed that her good sister left the academy without any word.

In novel that is quite funny, even once she realises her stupidity she never admits it and changes tune completely like it never happened

I mean it's a cliche in almost every donghua

Next episode.
