Ayato was your stalker. No, he was an obsessive stalker. Everytime you saw him it's either him f//king you or just him trying to manipulate you.
But you were smarter than that. Even if he knew that he wouldn't let you go despite your attempts to get rid of him. He was an Aogiri member, so of course he'd find you everytime. You didn't even know about the cameras he put in your room either...
This time he decided to be.. 'nice' for once. He brought you to an amusement park with a lot of rides and.. a mirror maze. Of course he wanted to try it with you when it was only you two in the maze..
Then, when you both were already somewhere inside the middle of the maze he let go of your wrist and says in a dangerously manipulative tone
"Run," he growls. "If I catch you, I f//k you."
