While I can’t say for certain, I think she’s gradually developing feelings for Yuushin (Think back to when she started pouting in ch.9 while Yuu was texting Koharu.) Whether this is because he reminds her of Miyu, stories that Miyu had shared with her (A sort of Prince Charming scenario,) or instead because he’s treated her with quite the fair degree of respect. I figure if she has already, she’s too emotionally stunted to properly realize it for herself, considering all but certain she had an extremely abusive childhood, and adding on to that, having her one anchor of normalcy ripped away from her.
Perhaps we’ll see her eventually start to let go of her pain and anger, keeping up the theme of acceptance with the assistance of Yuushin, but that is yet to be seen.
Regardless of any romantic attraction she may have, I think it’s pretty well certain that she at the very least cares for Yuushin, and doesn’t want him to suffer the same fate as Miyu.
