Hiyoko still holding back, it hurts her more than saying what she should. Tsugumi feelings for Otone changed, at first he made a story about her, but then completely different one, moving forward.
It's not selfish if he doesn't hold her in his heart as he used to, that vision Tsugumi disappeared as he get to know Otone real self.
Poor girl, hope she tries to confess once again or better yet, Tsugumi does it first as he basically also wrote about her in the second novel.
At least Nico said goodbye...
Thanks for scanlation!
