Yash agreee
i don't think anyone sees her as a threat, i think it's more about the really unhealthy way she's going about it, like sure she can have a crush and she can be a plot device for jealousy, but what really annoys me about her is this mindset of "he said he has a girlfriend but i don't care, i'm gonna keep pushing my feelings onto him until i get what i want!!" which is just... i don't like characters (or people) who think like this, so i'm big mad at her xDD
I mean the guy told her he has someone else and she is like "it a challenge! I totally going to steal him" is so annoying and disgusting to me even if she is not a threat to them at all. she still annoys me to no end with her mindset ╮(￣▽￣)╭
I mean yeah she is annoying but people do be really angry at the girl in the comments xD I don't think she's a big threat at all she is just some brat. And this manga is not that over the top like some. I mean what is she gonna drug him? Hold him at gunpoint? I doubt it he is not even taking her seriously xD
I think she's just a plotdevice for the uke to get cutely jealous over :3
