You clearly don't understand the point of this manga. Yes, she herself knew that her behaviour was quite promiscuous but her first relationship was extremely sexual and had no real closure. She was an absolute virgin who was with a player so she didn't know relationships were not supposed to be so sexual. Then she dated everyone else with the perception of sex being the main goal and everyone else treated her as such but due to the lack of actual feelings they got tired and broke it off. It would've been a perpetual cycle if she didn't learn otherwise. And she did, by meeting new friends and Koga

Lmao in all the years I've been on mangago, I've very rarely come across comments with this kind of like-dislike ratio. It's perfectly natural to have and express an opinion but maybe do it in a way that doesn't sound as much like you're shaming someone next time? xD Objectively, I don't think there's anything wrong with people being casual about sex, it's just that you personally can't stand it at all lol.
Btw I found an expression for it that doesn't have a connotation, in case you wanna discuss this topic again, but without pulling as much hate sometime in the future xD: sociosexually unrestricted.
Definition: "Sociosexuality, sometimes called sociosexual orientation, is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals who are more restricted sociosexually are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who are more unrestricted sociosexually are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness." (From wikipedia)
If you were to call her a slut or promiscuous, etc., you'd be right per definition, right about the "facts". But it's the way you interpret the facts that is often of the most importance. She's casual about sex but in essence, there's nothing right or wrong with that. At least in my opinion. It's kinda humans' thing to put their own moral spin on things and judge this and that but isn't it kinda more pleasant to just keep a comfortably distant and neutral mind?
Anyway, "sociosexually unrestricted" definitely isn't a common term but it can be quite nice to expand one's vocabulary a bit to make for nicer communication :D
Well u all saying that's a cute romance but from the 1st chapter she giving a slut vibe. Like, who the fuck go 3rd base on their 2nd day of their relationship. Moreover, she's being in many relations which never even lasted a month.
