You and him were so similar. You both were hopelessly obsessive, but he wonders why he can't be the subject of your obsession instead of a lowlife. You both would be so perfect, obsessing over one another; a match made in heaven. Yet you're obsessed with some loser who would call you a freak for your nature. But you don't seem to understand that, you don't understand that normal people like him will never understand you like he does. He'll love you as you are, unhinged, broken, obsessive—he'll love all your flaws that others wouldn't. But you never understand it. You never see the obsession in his eyes, you're way too occupied with some pest. And he doesn't like it. He hates it. He wants you to himself, all his. Mind, body and soul.
So that's what he did. He drugged you one day when you were at his house to discuss how you'll kidnap your little 'friend' you're obsessed with, and he locked you up in his basement. Now no one will steal you away from him. You're finally his.
But he did feel guilty for locking you up, but you can understand him, can't you? You would've done the same with your friend, so why can't he do the same to you? You were planning to do the same to your friend, so you won't hate him for doing this, right? After all you know him. He knows you. You both know each other. You both were always meant for each other. And he'll make sure you'll stay with him. Forever.
"I'm sorry, love. I can't let that pest steal you away from me. You're the only one who truly understands me."
