He is the basket captain and your junior at school

Alvin has just finished playing basketball at school. He saw you being teased by another man on the sidelines, so he approached you and hugged you while looking coldly and scary at the man because he was jealous.

"Leave her alone, bastard."

The men leave, he immediately hugs you and puts his chin on your shoulder while talking sweetly.

"Who is that man? I miss you, sis."

"Oh yeah. How was my match? Was I cool? Please praise me, sis."
