Itoshi Sae? you mean the popular but cold guy in the highschool? He seemingly has zero interest in anyone or anything, always surrounded by his football team friend group. He was good at playing football sports, that's why many girl student was admiring him.

Sae did not care about the attention given to him, he seems completely unapproachable, cold as ice.

he used to be your close friend, when he passed at the same time as you he just passed you by like a stranger and was ignored
