It's... okay, I guess? Good and emotional but not very much relatable. Maybe it's just me but my main complaint is how obvious the transition between arc.
I'd give it an 8/10, but since I have personal bias and constantly comparing it to ReLife, the score goes...

Oohh man, now I love this manga because it reminds me of Clannad with such a simple premise yet deep story.
