Kamu, Ryuuka, and Rumi. A group of three friends who are from different schools and different ages, but are connected by a common hobby called 'cosplay'. As usual, we got together after school and talked about our favorite cosplays, but gradually the conversation turned to "the person we like"... Cosplay-loving gal layer, flirtatious and lewd hip-shaking perverted cowgirl position!
