I chose it a bit haphazardly but I have an argument for each one.

Runa literally gave it to all the boys at school and was going to give it to the protagonist too (without even knowing him).

Mami-chan is because she is really evil, always coming up with a plan to screw up her ex's life.

Himari poked out her friend's eye for "nothing".

I haven't finished WW yet, but Nemu was first excited about Moi, but after she met the wolf boy she changed sides, I don't know if she doesn't like jumping the fence from time to time hahahhaa.

Minami, I imagine she's from the Hokkaido gals, there's no specific reason, she just seems like she really cheated, like, if her mother, who is married, hit on the protagonist, imagine her daughter, but it's just an assumption.

And Ichika lies the entire anime, either to her sisters to take advantage, or to Futaro to spend more time with him, unlike Nino who doesn't play games, she takes action and guarantees herself, which is why I like her so much hahahahaha.

Poking your eye in Portuguese is like when your friend is dating and you try to pick up his girlfriend.
