Obsession

Chapter 1

Drip, drip. The rain fell down, beating rapidly against my back. Like swollen tears. I looked up at the sky, the dark clouds like steam rolling out from a train, and then at the door in front of me, the one I never thought I'd have to see again. Here I was. Kida Masaomi. And why was I here? Well, it's a bit of a story...

A couple of months ago, my best friend moved here to Ikebukuro from our old hometown. Mikado Ryugamine. A straight A student and a mister goody-two-shoes (Not to mention bad with the ladies). From that moment on, I decided to teach him the ropes of the city. He was simply amazed with everything. And he had good reason to be, there was always something going on in our good-old Tokyo. What, with the black rider, all of the color gangs, that Heiwajima guy, and not to mention all of the hotties...! Wait, hold on a sec, I'm getting off track. This place just does that to you. Anyways, shortly after he moved here, we started high school. I thought everything was going to be just like it used to, during the innocence of our childhood when it was us two up against the world. But then she came.

Anri Sonohara. Average height, glasses, nice tits. She was pretty much like every other girl, but Mikado saw something in her. It's just like...a spark went off in his little head saying "she's the one." I didn't really get it at first, but I just went along with it. I mean, she was hot. Eventually, it was the three of us. Well actually, it was the two of them awkwardly trying to flirt with each other and me standing by the sidelines. And if there is one thing that Kida Masaomi didn't do, it was by-standing. So I would occasionally (okay, maybe not "occasionally") poke fun at Mikado. Saying things like, "Whoa, so you really do have the hots for her!" I didn't realize what I was doing by blurting those kinds of lines out, though. Slowly but surely, they started to become closer. And I didn't know why, but I was enraged. At first, I felt like she was stealing my best friend away from me. I mean, who wouldn't get angry at that? But, I came to notice that it was more. Much more.

Whenever I thought of her, I cringed. Whenever I though of him, I sighed. And whenever I thought of them together, my stomach started to hurt. The closer the two of them got, the more I wanted to hurl. Signs kept appearing to me, but I dismissed them as nothing. But then, that day came. It was just about a week or two ago. The three of us were walking home together, as usual, but when we dropped Anri off at her house, she leaned over to Mikado and gave him a quick peck on the lips. I was stunned. He was just as dumbfounded. As soon as she slipped inside, I felt my blood boil, and the first thing I thought of doing was slapping her. But I didn't get why.

So, me and him walked the rest of the way to our homes. We didn't talk much. Whenever I tried to start a conversation, I would look over at him and see a stupid grin plastered on his face, then drop the subject. We said our goodbyes when we passed my house, and I spent the night thinking. Thinking of what these conflicting feelings were inside of me. My thoughts trailed to so many places, but they all came across the exact same conclusion. I didn't want to believe it, but all of the facts were there: I was in love with my best friend. And a guy at that. I just couldn't help it...that goofy smile, the way he gets flustered so easily, all of the good times we've shared...everything came down to it.

Really, imagine that. The incredibly fun and flirtatious Kida Masaomi...was in love. I bet you're wondering why any of this has to do with my state right now. Let me explain a little better. I found out that I was in love with my best guy friend, but he likes this ugly whore we have to hang out with. (You all can see just how fond I am of her at the moment.) Said whore also likes him. Common sense says that I can't be with him if she is after him, too. So what, pray tell, do I do? I am not just going to sit around quietly, that's for sure.

After I realized all of this, I also decided that I would need help. And there is only one...person (I don't even know what he is...) that I could think of to help me. This reasoning has lead me to where I stand right now. Sulking outside his office door in a thunderstorm. I swore to myself that I would never come here again. Slowly, I force my hand to reach for the bronze knob that once turned, will change my life, hopefully for the good this time. There will be risks, I know this, but I'll have to face them. This is my decision, it is what I want to do.

I turn the handle to enter the infamous informant's office. He sits in his swivel chair facing the window, but I don't have to see his face to know he is grinning widely.

"Kida Masaomi," he starts, his words like poison to my ears. "It's been a while."
