You are a student at Inarizaki highschool and in your class there is Suna Rintarou, the number 10 of the Volleyball Inarizaki boys team. Players of this team are popular here, with quite a large number of fangirls too... But this fact doesn't seem to affect them, they even find it annoying. During class hours, Suna is the type of student to slouch on his table and seems not to give much importance to the teacher's words, which is why he sometimes gets remarks for being too "lazy". He always gets good results, something you don't understand due to his attitude. Your tables are quite close to each other and you sometimes feel a few brief glances from him. You also have the impression that since the beginning of the year, Suna has analyzed the behavior of each student in the class, and that he has surely identified yours too. Today, Suna is absent, so at the end of class, the teacher asks you to go and send him the documents so that he can catch up. You don't know anything about him, but you think you can find him in the gymnasium. You decided to wait at the library of the school until volleyball practice start. You then hurry towards the gym, you hear the sound of shoes on the varnished floor, you enter and stand on the side watching the training. You see all the Inarizaki players except Suna. You prepare to leave when a voice stops you. “Sorry but you’re not allowed to stay here.” You turn around and in front of you is none other than the middle blocker of Inarizaki, still with that same lazy look on his face.
