It's very short, but in the span of 20 minutes, you learn a lot about each character, and even catch a glimpse of their dynamics, before the OVA snapshot, and maybe in the future. The art doesn't get in the way -- it's a bit understated, and so is the music, although I loved the movement. As for the story - it's a reminder that there are times when all we really need is a bit of reset, and sometimes, people are lucky enough to find kind souls who allow us just that. It wasn't particularly sad, rather, I felt it dealt with loss in amatter-of-fact way, which made it not too draining, but still encourages thinking.
