Sekaiichi Hatsukoi S2 6! Junjou Mistake wrapped up into one complete episode. I like Isaka and Asahina's story; the standard bocchan and his servant. They seem like the oldest couple out of both series. Especially if Usagi (from Junjou Romantica) is only 17 here. Maybe the grey-ish hair made Usagi seem older? Also find it nice that Isaka's professional competence is highlighted.
Kaseifu no Mita 2! Well, the father did get a warning from the housekeeping company. One of the sons is being bullied in school and asks Mita to kill the bully. On the upside, he stops her before she finishes the deed, and faces the bully himself. On the downside, the daughter finds out that their mother committed suicide after the father asked for a divorce. The second episode was a bit sluggish, but I think Mita is an interesting character.
