Wow, that was really good. I haven't watched the anime, but I got really into this, it was good.
The art was sort of rough tho, felt really shonen-ish with the style and expressions too. Idk the characters, idk if it'd be OOC or anything, but only considering what I've read/understood from this, the characters, the pacing, the dialogue, the feelings expressed were solid. The art wasn't maybe as cute as the sort of story told, but the feelings you end up with amount to the same. It's sweet, heartfelt and satisfying.
