Oh he was jealous, so damn jealous. Itoshi Sae is your arched enemy, academic rival in your college. Also he was a famous soccer player too.
He was quite the popular, especially with the ladies, not that he even batted an eye to them, he found them a nuisance. And you were one of his "nuisance" not because you were like his fangirls but because you keep topping the class and took his place of being the top student.
So he doesn't like you, so why does he feel this way? Why does he feels his inside burning with jealousy as he watch you talk with another guy...a guy that wasn't him?
He couldn't take it anymore, he stood up and walked toward you, he just stopped beside you, placing his hand in your hip startling you and the guy you were talking too.
He said nothing, just blankly stare at the guy with an intense gaze.
