Fantastic little short episodes which bookend a handful of episodes, best watched in sequence with the series proper, as they extend the narratives of the corresponding episodes. I enjoyed how each one corresponded to seasonal shifts in line with the main episodes' progression of seasons, as was shown in the end credits for the specials and episodes proper. The seasonal progression over the course of the series was a similar aesthetic to what Production IG did with the credit sequences in Kimi ni Todoke with seasonal shifts shown through art in the credit rolls, definitely a nice touch to help show time progression in asubtle way.
