Chizuru invites Kouta to come to a fancy hot-spring resort up in the mountains in order to enjoy some time alone with him, but her plans are thwarted when Tayura, Akane, Nozomu, and others decide to tag along. To Kouta's surprise, the resort is run by none other than Chizuru's mother, Tamamo Minamoto, the same lady who sent the snow womanYukihana to test their relationship just days earlier. Things get rather complicated when Tamamo, much to Chizuru's displeasure, decides to once again test the bonds of Kouta's relationship with her daughter by mixing a "special" brew that makes Kouta fall head over heels for Nozomu. Can Chizuru win Kouta's affection back? Or will Tamamo have the last laugh?
