Does Kuromi Hate My Melody Novels & Stories

Melody. "What the fuck are you doing here?" Serena looked surprised, but then her facial expression slowly turned angry. "Did you think you can keep me away forever?" Melody chuckled. "I never wanted to see you again. We are not lovers anymore. And you aren't even my friend!" Serena declared. "Oh, come on, baby. Don't be like that. Don't you remember the fun we had?

"Yes, it's a melody from Kitaro." And in the end, the bible page shifted to the old testament. "Even though the melody is so good, the violin can't play the melody itself, because creating the melody has to be in collaboration with the team." I really believe in my analysis.
