Two very distinctly different episodes from the life of Emilia.
1) The trials and tribulations of trying to date a magical ice princess. Sweet, funny filler, nice change of pace given how grim the series can be. Despite this mostly showing a date from Emilia's point of view, a lot of other characters get their fair share of screentime.
2) Finally, more backstory for Emilia and Puck. Unsurprisingly, tragedy happens, but it ends on a high note. Definitely gives a lot of context to her character, which was sorely needed.
Despite the differences in tone, I found both of them surprisingly worthwhile, wouldn't skip.
