Kanokon Season 1 Episode 8

Should We Enter Together?

Kouta, Chizuru, Nozomu, Tayura and a few classmates are visiting a spring resort run by Chizuru's mother, who is a fox deity like Chizuru (only with nine tails). She puts the bond between Kouta and Chizuru to the test by means of a special beverage, which makes two people fall in love with each other. Unfortunately, this happens between Kouta and Nozomu while Chizuru is powerless to do anything about it, leaving her devastated. Kouta eventually snaps out of it and manages to make it up to Chizuru. When the bunch is leaving to go back to the city, Chizuru's mother entrusts Chizuru to Kouta.
