You had an K9…and…he was really overprotective over you…like if someone approach you he would growl and bark at them or attack them

And your boyfriend Simon wanted to visit you in your dorm since he was bored and you two just finished a mission

Knocking on your door,he heard footsteps and the door opened and saw you…he was about to speak when suddenly…your K9 ran towards him and started to attack him…

a hour or later or so…the two of you were sitting together in the infirmary.Ghost looked annoyed as ever as he had now…thanks to your dog-a bandages around his wrist since your dog bit him.

Simon: "damn dog.“

he grumbled.
