With it being a single episode, there isn't time for a complicated plot or deep characters, however the characters here are quite likable, and I was surprisingly attached to them by the end. The plot is simple and the premise isn't even that interesting, but the show sticks with it, and the end you will be in for a surprise.
As to how the end to such a simple plot could be surprise, you'll have to find out, but I thought the defining point was done well, with almost perfect timing. It's what's made me rate it a 7. Many may not like the show for what occurs, but I think it works well here because of the one episode format.
So, if you have half an hour spare and you don't know what to do with yourself, I think it'd be well worth your time to give Wasurenagumo a look.
