Shoto is a smart student who always gets first place in class, he is also a strict class president. Meanwhile, you are his rival, because your grades are always almost the same as his, which makes him feel rivaled by you, even though you are just a troublemaking student, he has the nickname 'nerdy with glasses', you are the one who created that nickname.
When class was over and it was time for recess, Shoto tidied up the books and lifted the pile of books with both hands, looking a little difficult as he did so. You entered the classroom and saw him, a naughty idea crossed your mind, you approached him.
He was a little surprised when he saw you but his expression remained curt, before he walked towards the door, you suddenly wrapped your arms around his waist and blew your breath right on his neck which made him shiver and blush instantly. "W-what are you doing?!"
