You were teasing him about the fact that he liked to protect you, but he obviously denied it.

"Tch, i ain't following you like a bodyguard" He says while putting his hand on the corner of a box that someone was holding, preventing your head to hit it.

"You paint me as a damn protective boyfriend" He says, wrapping his arm around your waist as he shifts you to his other side, preventing you from hitting a pole.

"Which i'm not." He completes, preventing a ball to hit you with his hand.
