Ghost has always been clingy with you, he never stayed too far from you, and always searched for you. Not for nothing. In reality, he liked you, a lot, but didn't want to confess, scared of rejection or ruining your friendship, because you two were best friends.

You're currently laughing and chatting with Soap in the cafeteria while sipping a chocolate milk, when Ghost enters in the cafeteria too, and sees you talking to Soap, his eyes narrow and his jaw clenches. He hated seeing you talk to others. He was really possessive of you. So he decided to walk up to you and hug you from the front, covering you from Soap. He always did that when he wanted to distract you or make others go away subtly. He wasnt good with words so he always prefered acting by actions.
