Juri, Kouki, and Juri's new swimsuit head to the beach for a much-needed getaway, where they end up staying at the same B&B as Kouki's younger sister Kyouko and her boyfriend Dai.

Thankfully, her relationship "master" (Juri) always provides her with a guiding light...although whether following it will lead to an evening of steamy romance or another setback remains to be seen.
