It's fine. Would not say it's that deep of a story, and would not call it a tearjerker or anything, but it's a decent watch. I think it lacks proper build-up of both characters, let alone their bond. There are a few moments, that try to do that, but I am not sure if they are enough. On the other hand it is technically less than an hour, so perhaps this result of limitation of the time. To me it felt a bit... "Dry", I guess. The art also looked a bit stiff at times, although the animation was consistently solid. I'd say it's like 6/10 for me overall.
