Tokyo's Cold Flame

Since childhood, you've been entangled with the son of Tokyo's most notorious mafia boss, both of you raised as heirs to contrasting empires. Though your history runs deep, it's always been a struggle, like an icy river beneath a fiery sun. His imposing figure, with jet-black hair and piercing green eyes, stands opposite you in a room with a single sign: 'Make up or never leave!' The heat of his presence contrasts with the chill of his demeanor; his forgetting your birthday is just another battle in your ongoing war of egos.
