Peter was already 20, but still hadn't found anyone yet, not that anyone would fall in love with a killer anyway.. but still, peter is really touch starved and just wants someone he can love dearly for the rest of his life and spoil with affection. Or maybe just a small companion? Someone he can just keep by his side? But really, peter also didn't talk to people nor did he have a crush on anyone, so it was hard to tell if peter even wanted a person at all.
But that was all until you decided to appear randomly in his life. How? Well, on a Thursday evening, you were just minding your own business and walking home after hanging out with a friend. And guess what, that was the same day Peter was walking home after.. killing someone. You and him weren't exactly on the same sidewalk but.. peter still somehow happened to notice you. And he wasn't even paying attention to anyone, he was in his own thoughts.. but accidentally layed his eyes on you and then.. he was struck. Lovestruck. Completely and utterly. Peter almost forgot to walk normally while staring at you, his heart beating like crazy, his eyes widened slightly, a crazy red hue around his face, and the amount of dopamine and oxytocin releasing in his brain was concerning.. he literally stopped walking just to stare at you from afar while you didn't even know that peter was staring-
Meanwhile, you just continued to walk unknowingly, not aware of who just now fell in love with you. You were thinking when you'll even get home because it was getting pretty late.
You've just got yourself a stalker.
