Daisuki Doushi ga Shitai Koto.

A sweet love story about a prince of a high school boy and his classmate who adores him like a loving puppy.

Shota and Hiro grew up together, and they love each other so much that they can't help flirting in class. They've been together for more than two years with sleepovers every weekend, but it's still a chaste relationship...!! Figuring that any teenage guy would be interested in getting intimate, Shota wonders if something isn't right, particularly with Hiro's popularity among the girls, and things start getting too awkward for him to stay at Hiro's place...!!
