The bookworm on the team

MSBY is the furthest from normal out of all the V-league teams. The perfect example is Atsumu Miya, a loud, annoying, blond setter, who is considered extremely attractive (by a certain ace on his team)

And there is the total opposite of Atsumu, Sakusa Kiyoomi. Who is a big bookworm. He carries around books everywhere and it's always a crime story, written by Itazura. He started reading the series in highschool and it was his favourite ever since. He was always the first one to buy the book and try to solve the mystery, but he never could guess the right person.

One day Atsumu guessed a random character (or so Sakusa thought) to be the murderer and he was right. And due to assuming the blond was dumb, he didn't considered the option that he was the writter of his favourite series.

How will the story go?
