My little mafia girl

This is about Kim Y/N from Korea. She's one of the most dangerous mafia bosses in whole Korea and Japan. Y/N's the mafia boss of the dragons, every member that's in the gang needs to have a tattoo of a dragon and a flower on their arm, leg or ankle.
She then meets Mello and falls in love with him but she wont show her own feelings so she kept it in.
