Felt bad and told the FL about the ML’s feelings and to talk to him even after he begged her not to. What more should she do after finding out? Idk when they were in school no one knew the FL actually liked the ML until that botched confession because FL kept it a secret because the ML asked her to. And imo Arista only saw the ML as a friend who respected her love for swords and understood her, not realizing that he “liked” her. I doubt there were any boundaries to cross since they all generally hung out together. And Arista and ML were in the same swordsmanship program. So they trained together.
If I had two friends, one who liked the other and the other clearly rejected them and they both looked like they just wanted to stay friends. I’d be keeping my mouth shut about bringing up those wounds.

You fucking knew FL feelings all this time lol then just doesnt care ML liked her???
