It's not about non-virgin or virgin, it's about the portrayal of a one-sided love(depicted depressingly) over a long time span. Being a simp is about the guy and his behavior, nothing to do with the girl at all. She could've been single the entire time, it's more that she was uninterested in him over the span while he held onto a weird obsession is what makes it come off simpy or at the very least odd/creepy. I'm not a purist so don't get my objections conflated with obnoxious vanilla virgin-only purists. Simp or not it's still not fluffy in my professional opinion, and as a fluff connoisseur I cannot give my seal of approval.
