"WHAAAAT??" Misa screamed, twirling one of her 'cute' blonde bunches around her hand in agitation. "You cannot be serious!"
Light sighed deeply, running a hand through his neat brown hair. It had taken him the good part of the last half hour for him and L to persuade Misa exactly why they had to be handcuffed together. And now she had discovered that L would accompany them on any dates from now on.
"Look, Misa," he said, putting a hand on her shoulder to calm her down "This is really important for me to clear my name, okay? Wearing these?"
He held up one hand to show her the thin chain linking his wrist to L's. The scruffy haired detective was watching the scene with amusement from his chair.
"I knooow..." Misa whined, wrapping her arms around Light's free one. "But can't you just take the cuffs off for like an hour a week so we can be together?"

Light sighed impatiently, shooting L a look. Light didn't relish the idea of being chained to the other man, but if it meant he would clear all suspicion of being Kira... and at least it was a good excuse not to spend time with the insufferable Misa-Misa.
"No, Misa, as each time that happened, the percentage of Light being Kira and you being the second Kira would increase." L replied calmly, leaning over to his computer desk to grab a wrapped candy. He unwrapped it delicately, popping the sweet into his mouth, and smoothing the cellophane out on the desk. He folded it neatly into a triangle shape and dropped it onto a pile of identical bright wrappers. When he looked up, Misa was wearing a massive pout and hanging around Light's neck. L rolled the candy around his mouth, savoring the sweet taste.
"Look, we really need to be getting back to work, so if you don't mind, Misa..." he said. She blinked, and Light gently removed her arms, kissing her lightly on the forehead.
"I'll see you later, okay?"
"Have fun, Light!" she said, her chirpy attitude returned. L watched her skip away, and then returned his gaze to Light.

"You are quite the actor for somebody who says he finds Misa-san annoying."
Light looked at him with a frown.
"So I have experience dealing with girls. Comes from being popular, it doesn't increase the chance that I am Kira."
L smiled, reaching for another sweet.
"I was merely remarking on your acting abilities. I never mentioned Kira. You are much too suspicious, Light-kun."
"Well it was clear what you were thinking," Light replied, refusing to be caught by L's tricks. "Because it's all you think about."
L blinked, tilting his head to the side to look at Light.
"Well then, say I was remarking on how this may increase the probability of Light-kun being Kira. Would you not agree that if you were Kira, you would be able to fool me as easily as you fool Misa that you are in love with her?"
"No." Light replied "Misa is not expecting tricks, nor does she want to look for them. She is in love with me, and wants to think that I return her feelings. Therefore she is easily to fool. You on the other hand are not in love with me. You are a detective who is an expert at tricking criminals into revealing secrets. You are ready for any bluffs I may throw at you. And what is more, you are looking for them, slipping traps into the conversation which I would surely slip up on, were I Kira. Yes, Ryuzaki, I am a good actor, but not that good."
Apparently satisfied, L nodded. He turned away from Light to his computer screen, pushing another sweet into his mouth and frowning in concentration. Light watched him for a moment, before turning to look around the room.
"Hey, Matsuda! Is there any coffee left?"

The day passed as any other would do, except that Light and L had to go wherever each other chose to. This was not difficult as they spent most of the day working, but made going to the bathroom a problem. Always prepared, L had a solution in the form of a specially designed cubicle with space to hook the chain over so at least they had a little privacy in that respect. Light was beginning to get used to the annoying clinking and unusual weight on his wrist, and even Misa had stopped trying to persuade L to let Light go for dates when she came back to headquarters during her lunch break from filming her latest commercial. Light knew that it was only a matter of time before L realised that Light Yagami could not possibly be Kira. And L was pretty sure that soon he would find something that would give new evidence that Light Yagami was Kira. He bit the skin next to his thumbnail thoughtfully, looking at the back of the teen's head. It would only be a matter of time.

Sorry, first chapter's kind of short. I just got to a good place to stop for this one before the good stuff happens. The next one will be better, I promise. Stacks of sugar cubes for everybody who reviews!
