Watched it yesterday.
I just feel like there's nothing to say about such a short clip. There was no real message hidden, just a really cuddly thought about friendship. The focus of the item on sale is the figurine anyway, and I'm not sure where I heard this but there's supposed to be a light novel (or a manga?) about it which might reveal more story. But who knows what the future may bring. Maybe even a TV serialization.
I really really wish this to be longer. :|
