I still don't trust Gotou. She has been playing with Yoshida's feelings, no matter what sensible reasons she's telling herself she supposedly has. If she has suffered some setbacks in the past, it hasn't got anything to do with Yoshida, so why should he pay the price for it? It would still have been okay if she stuck to her earlier lie and didn't approach Yoshida anymore. With Yoshida none the wiser, it would have merely been the usual story and he would have got over it eventually. But no, she didn't leave it at that, yet at the same time she doesn't have commitment either.
The only positive thing Gotou has achieved in the story so far is this conversation with Sayu. It's quite obvious Sayu does need to think about her own future and find a way to deal with her sucky past.
