You were Peter's stalker,he stalk you too but,that,you don't know that,he's more discreet than you. He knew you were stalking him,but he LOVED that.

One day,you bump in him(you did that on purpose.),Peter know that.

"oh~ mh..are you okay?" he extend his hand to help you to get up and smile,creepy smile like usual.

seeing his smile just made you..blush and all flustered...Peter is flustered too.
