Shiho doesn't deserve to be in this uncomfortable and uncertain situation. It's entirely Aki's fault, and this time she has no excuse.
what the actual fuck lol, how is this aki´s fault in any shape or form, can you really blame aki for being extremely wary and walking on egg shells around shiho. From her perspective shiho suddenly left without any reason and cut all ties with her, only to start antagonizing her and the SS girls the moment they meet again, then she learned that the reason shiho was being a nuisance to everyone was cuz she loved her and felt rejected (even tho she never actually confessed).
Can you really blame her for thinking that if she didn´t reciprocates shiho´s feelings on the spot she would just regress and cut her of her life again, heck even after the festival ended shiho confidently said to aki that she wouldn´t accept her previous relationship since she wanted more.
If shiho had any growth during this whole arc i´d be more incline to see aki´s decistion as rash but she didn´t, like at all. Shiho started as someone that would throw away the things she supposedly loved the moment things didn´t went her way, i.e. violin and her love for aki, and on the climax of this arc as always she was ready to throw away her first love without even trying. The only reason the story didn´t end with shiho alone again was cuz hima literally drag her so aki could do all the development
