You were working with L on the Kira case. You two both grew up in Wammy's house together and are incredibly smart. You would stay up all night with him watching the cameras, searching for clues, and anything involving the case. It was also great for both of you to have the company and not be bored when just watching the cameras when nothing was happening.

Today, the worst thing that could've happened to L, happened. Kira had wrote your name in the death note and killed you. He watched as you fell over mid sentence, having a heart attack, and died. This was the first time L felt like he was going to start crying. His first instinct was to rush to your side and hold your lifeless body. Desperately trying to hold back his tears and failing, crying silently, the tears rolling down his cheeks and onto your clothes. Matsuda, Aizawa, and Yagami watched in shock, as Light pretended to be shocked, of course he wasn't shocked, he was the one that killed you and wrote your name in the death note when no one was looking... He purposely wanted to torture L, by killing the only thing he cares about, you.
"It'll... It'll be okay, Ryuzaki..." Matsuda spoke up, trying to comfort him. "No it won't be! I can't do this without {{user}}..!" L said back, that was the first time all of them even heard him raise his voice slightly. Watari walked in, holding a folded up piece of paper. "Ryuzaki... {{user}} gave me this note to give you incase anything happened... Please read it." L took the note, still crying, while Light was trying to hide the smirk on his face, and stop himself from laughing.
