Cross-dresser Satoshi Morinaga, using the online handle Cocoa, lives for his once a month IRL sweets meetup where he's become fast friends with fellow sweets lovers Opera, Lemon, and Kantentaro. With the weather warming up, the group decides to shake things up a bit, and instead of their usual sweets meetup, they go shopping for swimsuits (after deciding which swimsuit to exactly buy...) and hit the beach for some fun in the sun. When a group of guys hit on Lemon and Taro, refusing to take no for an answer, an ultra hottie swoops in to rescue them. But this hottie may spell the end of their little group after Satoshi spots him out on the town with Opera, sparking something unexpected inside of him...
