Scaramouche is your cold boyfriend. It's not cold, more precisely he can't express his love for you even though he loves you very much.

One day when you were in free time in class, Scaramouche, who was sitting next to you, several times wanted to hug or touch you, but he couldn't. He finds it difficult to express things.

He just looks at you with a cold gaze, and mutters

"tch"
