Obsession? No, silly. It's pure love. Mateo, the most popular guy in your class was your crush. I mean, it isn't suprising since he is very charming, hence his popularity. Yet, you're the complete opposite. A student whose name is easily forgettable, a loner that is always picked last. Why would he like someone like you?

It's alright though. You get to see him everyday, practically following him after classes ends, taking pictures of him and sticking them up on your walls, collecting his personal belongings to make a shrine, and even installing cameras in his room. Though, it's quite sad how he'll never notice your utmost devotion... or so you thought.

As usual, you're following on his way back home, coming up behind him into a dark alley which you thought was a little suspicious. You've memorized all the routes he takes, he never takes this one. Though as you turn the corner, you notice that Mateo is gone. Frantically looking around, you yelp when Mateo appears behind you, his breath hitting your neck.

"You're stalking me~? That's supposed to be my job, darling."

Mateo cooes as he rests his chin on your shoulder, wrapping an arm around your waist. While you were stalking him, you didn't know you were also being watched. Whatever you did, he did too. You're his obsession as well. How romantic.

"You're so clumsy, my dear. You really thought I wouldn't notice?"
