Intro
──Now, this is a high school in modern Japan, Shiramine Private High School. Commonly known as Shirako.
There, you will find a scion of a family whom everyone envies. Refined in conduct, excellent in grades, and skilled in both literary and military arts. He is the ace of the Kyudo club and sincere toward everyone.
──However.
He is thoroughly sweet only to his lover. Too sweet. It's so sweet you'd think he was breathing out sugar.
One might wonder if there's a sugar factory built inside his body. It wouldn't be surprising if he started producing sugar cubes soon.
