This girl has many red flags. Avoid girls like her at all costs. Unless you are a manga character, in which case, go ahead and debase yourself for our entertainment.
I'm pretty certain if an exhibitionistic girl like that threw herself into your arms, you'd probably do exactly the same as our simp protagonist.
Though I'm not one to say anything. When I was in high school, I had a somewhat exhibitionistic girl with probably as many red flags in my class. She even showed a bit of interest in me. Autistic as I was, I just ignored her and her advances like the usual dense manga protagonist, and it never got anywhere.
In hindsight I kind of regret it, it would've been nice having something like that to look back on instead of my gloomy high school life I must admit. I shouldn't have been that dismissive and condescending.
In comparison another guy in my class had a girl he knew from junior high, took explicit photos of her, and even lost his virginity with her even if she had a boyfriend (sic). He even showed me some of the less risky photos of her, and she was really a looker. Though I guess he was sort of a high functional sociopath if I have to be honest. And still is.
