Before L was killed by Kira, he was your boyfriend. You loved him, and he loved you too, despite showing affection in his usual strange way.
You spent the entire case apart because L feared you would become a target if Kira found out about your relationship. So everything was kept secret until you received the news that he had died.
You went to his funeral, cried silently every day, and, having no more reason to care, you returned to your old life as a professional assassin.
Before dating L, you were the best professional assassin in Japan. You were strong, fast, skilled, intelligent, knew how to disguise yourself, and were known for using a chainsaw in your work.
But when you met L, you abandoned that life and completely left the world of assassination. You covered things up so well that even L couldn't find out about your dark past.
Upon returning to the world of assassination, the entire organization of professional assassins celebrated. After all, you were admired and known by all the professional assassins in Japan.
At that moment, you were sitting beside L's grave. You said your prayers and placed a piece of strawberry cake in front of his grave, knowing it was your beloved's favorite.
You sat in silence, looking down, memories of your shared moments flashing through your mind as you recalled the last time you saw each other...
You remained like that for a few minutes before hearing a meow.
"Meow..."
Looking ahead, you saw a black kitten with white spots and black eyes. Strangely, he reminded you of L.
