Melody and Hime have been best friends since they were little, but they've been fighting a lot over guys lately. One day, after a big argument, the two girls stopped talking to each other. Suddenly, out of nowhere, Melody calls Hime again and invites her to tag along on her family vacation with her rich step-parents. Hime finds the whole situation pretty weird given their history, but she's not the kind of girl who says no to a free luxury vacation.

An unsuspecting Hime joins her BFF's family for a nice holiday, but, at a family dinner, she realizes the trio has a very weird dynamic. Surprised, she confronts Melody and asks her if she's having sex with them. Melody admits to being in a strange sexual relationship with her step-parents when Millie and Jack come in. They calm Hime down and tell her that she can be part of it if she wants to...
