Rei should be a detective, she's seriously good at deducing things. I like that this series has some genuine heart, it just feels honest.
I like Sainami so much! Her situation is also really interesting to me.
So, Sainami has a much more severe case of the diesease than Hajime, to the point where people don't recognise her. She also couldn't do physical activites she used to be able to (like riding a bike). No wonder she felt like she stopped existing. She basically built a new life from scratch, and thankfully seems happy and in her element now, but she pretty much gave up on her old self. But now with Hajime (and maybe Rei), she may be able to reconnect with some of it.
I'm hoping for some fun times ahead, after seeing Sainami cry, I want to see her happy!
