You dont need to be family to care about someone tho. That itself isnt wrong but what wrong is her taking her own actions without the ml knowing or consenting.
Also she said "i'd like to be alone now" doesnt meant she needed time to think but it actually meant this conversation end here i dont want to argue any further i said what i said.
ML did scold her for making the account without him knowing but i dont think ML can get mad at her for caring about him. Thats why he didnt scold her for that.
There is something here. Sometimes people use the term "care" for way too many things that are harmful. She can care, but it doesn't take away from the fact that her CARE could have hurt a relationship. There is a limit to how you can express that care, and she is 18 already old enough to know. There is a sarcastic saying in my country "don't care about it so much that you kill it".
It's like you have a partner I am your friend, you are happy but because I care about you I will spread the information that you want another partner everywhere, and tell people that you are looking for someone new, because I think that is the best course of action gor you (to find someone that I find acceptable). I am also 18 and you are 36.
Don't get me wrong she is not Evil, I have seen people like that, she hasn't killed, she hasn't kidnapped, rape, sexualy assaulted someone, or tortured anyone, so to me she isn't evil, but she is wrong, and there is nothing wrong with taking my frustration for this character into writing. Plus she is really well written in the sense that you don't like her, but it is also the authors fault for writting her that way, when there where clues pertaining to her orientation.
All the people defending and saying that she was probably a closet bi or lesbian, their efforts went to waste, because her story didn't even include her sexuality or gender or anything really. The worst thing is that it was insinuated that she would do it because maybe she was bullied for liking a girl or because a girl liked her, and out of nowhere it came up to this.
The worst thing was that he did tell her, how the fuck was it any business of hers who he kissed, and she just said well... "It's my business because I care about you" ... how is it your business he is not even your family for tou to even think its your business.
What makes it worse is the fact that she went all high and mighty and told them to leave her alone because she was feeling bad about the fact that she knew what she did was wrong. That she needed time to think about things, like what the fuck do you have to think about? You knew when you did it it was wrong, you did it, when they confronted you, you got indignant and kicked them out because he did want to take the good thing you offered him, a d then you wanted space from them because YOU couldn't deal with things yourself.
This character is well done, to be hated of course. The thing is that they almost didn't scold her, not enough in my opinion for what she did and said afterwards. It seems they felt they where on the wrong about their relationship, and just left on a date when she kicked them out.
