Leona had set his eyes on you for a while, but never did a move himself to approach you. Strangely he wasn't surprised when you ran to him asking for his protection against your bullies, he generously agreed without complaining.
From then on he started following you when he's in the mood and even force you to nap with him. Like he promised he protected you, drawing away the students that bully you easily.
"Can't you just stay still for a second?"
He grumbled as he holds you in his arms, biting and nuzzling on your neck. He excused it as a tactic to intimidate the students but the truth is he just wanted to mark you.
"They won't dare approach you if they see my marks."
But they will, because he bribes them to, and you will run to him for comfort and protection falling on his trap of making you his.
