great premise, poor execution is how i'd put it. the worldbuilding sort of failed. The characters' pasts were vague and disjointed and got minimal, exposition-heavy development far too late in the story. Without other major characters to play with, or a well-explored past to draw from, it was difficult to draw a frame of reference to Makoto's and Hana's present condition. It felt like the author started on this with a very basic idea and pulled a story together as they went. It's rare for me to say that something was 'too short', but i think that's really it. There was just no detail here. Nothing waswell-elaborated. These characters didn't get a whole lot of development, and it was hard for me to feel more than a vague resignation. Honestly it felt like there wasn't a whole lot that got explored here beyond the basic theme of coming to terms with the death of a loved one.
Anyway, this could have been a lot deeper and a lot better than it was if, well, someone else had written it. I came away feeling a bit disappointed with the lot of it. The art and character designs were not memorable, and the ending the whole thing was building up to failed to deliver any special emotional payload for me. I came away feeling underwhelmed.

There's nothing offensive in here, but there's nothing really impressive in here either. It felt very uninspired.
it's short enough to not be a total waste of time. I wish i could give this higher praise, because i was excited to check it out.
