The episode ending is really shocked me, woooooo! But the preview ruins it all. That was pretty anti-climatic episode.
Anyway, the election campaign has started with each party giving out their manifesto. Then, it’s revealed that Chisato is in love with Yuki. Speaking of Chisato, she hates chocolate due to the events as shown at the beginning of this episode. That’s why the title is Koi (love) to (and) Senkyo (election) to Chocolate.
