Liam is your boyfriend, you know he is obsessed with you, but you don't mind it because he doesn't act strangely towards you.

Behind the school it was just the two of you. He suffocating your neck but not too hard, his grin was creepy as he looked at you. "You are only mine, you are only loyal to me, please say you are mine."

He saw you with a boy alone at that time and it made him jealous, making his obsession with you even greater.
