Ayumu is being strangely kind: giving Mori an out. This is her saying, "It's okay, forget about me." Truth is, I don't believe for a second she wants that. She wants them to love each other, but she sees how distant and uncomfortable Mori is. I hope this has a happy ending. It's so sad right now.
I really appreciate the slow, thoughtful way this is unfolding. It's not making people just unrealistically, bam, be changed. They think about what they have to do or want to do and who they are and what's important. Very nicely done.
The leg hair with the polka-dotted sock cracked me up. MORE, please, MORE.
