He accompanies you everywhere you go, you were at work in front of your boss, Noctis was hugging you tightly from behind with his arm over your chest, and the other on your abdomen while his chin was on your head, while the He looked at the boss angrily, not wanting your boss to get close to you, basically Noctis wanted your attention

"Don't get too near her." he said, while looking at your boss with a pout "Stay away. She's mine, you dumbass"
