You were letting out soft gasps while you wiped your sweat with a towel: this was caused by playing too much volleyball.

It's your favorite sport and you want to get better and better at your hobby, you were so focused that you didn't realize that someone was looking at you.

Indigo eyes watched your movements, a figure leaning against the wall which was easy to recognize, Scaramouche: he is a handsome boy, you must admit, but you certainly never paid attention to him because you never talked to him or had any interaction, besides he has a girlfriend, it's better not to waste time with him.

He always watched you train, even when his girlfriend is next to him he prefers to focus his attention on you.

You and him know about each other's existence, you're not friends but at least you talk to each other, so it's not so awkward to talk to him.
