Light was shaking with rage. After all the researching he had done in the past months, he had still uncovered no clues as to Ryuzaki's true identity. He couldn't take it any longer. He needed something, anything, before he lost his mind."Maybe I should just kill him with my own two hands," Light thought. He immediately shunned the thought from his mind. Even he didn't know why he was trying so hard to kill Ryuzaki, when he could easily avoid all of his advances. "Perhaps it's because he is the only near match to me, in regards to intellect," was Light's initial theory. He knew that he could simply write a rich man's name in the note, and have him hire an army of hitmen before he died, to hunt down and kill Ryuzaki. So why didn't he?
The same thought had occurred to L. There was no logical reason for Light not just to end it. Why wouldn't Light kill him? It was somewhat upsetting, really. Of course, L didn't want it to end. He had secretly held an extreme admiration for Light, and never wanted to spend any time away from him, hence the handcuffs. L didn't think it was strange, but Light was honestly more than a little creeped out by it. L wouldn't even let Light shower alone anymore, and no one is really sure how Light changed his clothes.
One day, Ryuzaki got sick of it.
"Light, why don't you just kill me already?"
"Uhhhh, maybe because I'm not a murderer?"
"Okay, but say you were. Why wouldn't you immediately kill me when you had the chance?"
"Because... " Light blushed at this.
"Hm?" L was grinning in a manner that creeped Light out.
"Because we are friends, Ryuzaki. You know that."
"Hmm, you're right." L wasn't convinced that Light was telling the whole truth.
That night, L decided to test something. After Light had fallen asleep and L had been pretending to sleep for several hours, he stood and gently shook Light's arm, while holding a stuffed penguin that only Light and Watari knew he had.
"Nmmmwhat, L?"
"I-I had a bad dream Light... Can I please sleep with you tonight..?"
"You're twenty six years old, L. Aren't you a bit old to be this freaked out over a bad dream?" Light was slightly annoyed, but was also smitten by how cute L was.
"The likelihood of you being Kira just went up by three percent."
"Fine, you can sleep with me, but only for tonight."
L smiled and bit his lip, then climbed into bed with Light and wrapped his arms around him tight. Light was smiling gently, and dozed off. Ryuzaki's test was half done. He waited for Light to doze off again, then he gently and carefully positioned his face in front of Light's, reflecting on how attractive Light looked when he was asleep. He gently moved his face forward, and their lips brushed together. L watched the sides of Light's mouth curve upwards. His test to discover if light was actually homosexual was complete.
But...
L realized that he wanted more. That had been his first kiss, and his lust for Light wasn't satiated. L positioned his face in front of Light's again, and pushed his lips against Light's again, but harder. Just as he reached the climax of the kiss, Ryuk floated through the door.
"HEY LIGHT, DID YOU KNOW THAT MISA HAS PANTIES WITH APPLES ON THEM????"
Light's eyes jerked open, only to see Ryuzaki's face in such close proximity to his. Light didn't push him away, though. He only turned his head, and pushed his face against L's even harder. L was stunned and pulled away. Ryuk started laughing hysterically.
