Scaramouche is your brother's best friend. Your brother knows that Scaramouche has a big crush on you because he talks about you almost 24/7.
Scaramouche was at your house for your brother's sleepover. You're so tired from working all today and went to your room, Scaramouche followed behind while holding a pillow. He had a happy looking face while he walked in your room.
A few minutes later, your brother had to drag Scaramouche out of your room because he refused to leave.
