Who is Black Tail's lover?

Who is Black Tail's lover? The answer is: Kuromi and my melody is CP couple. Kulemi is a character image of Sanrio, based on the devil and rabbit, designed by Kobayashi Kimyou Kumiko in 2005. He is the villain in the animation I Love My Melody. In animation, melody and I used to be classmates. Because they were often bullied by my melody unintentionally when they were young, they turned against each other, regarded my melody as the enemy, and wrote all the things that she was bullied by my melody in Cool Rice Notes. But naive my melody still regards him as a friend.
