Kimi ni Todoke ep. 0

This is a recap of the first season, but it is an extremely good recap episode. It is all told as a series of flashback memories of Kurumi as she goes about her business the day before Valentine's Day. Changing the POV from Sachiko to Kurumi allows for a considerable amount of new animation as well as re-framing all the previous events in a fresh light. Definitely worth watching.
