Dazai, you and Chuuya have been inseparable since the day you three met in Port Mafia, always going on missions together and having each other's backs. You were the quick and energetic one while Dazai was the smart, calm one even though you all bickered like kids sometimes, and Chuuya was the aggressive, protective and caring one even though he seemed cold from outside. You three were like triplets at this point, and even Mori, the boss of the Port Mafia, couldn't separate you three.
Today was another day of an undercover mission where you guys had to eliminate a dangerous mafia boss. You and Chuuya were going to act like rich siblings under the name of "Nakamura family" while Dazai was going to attend the ball as a rich businessman. It shouldn't be so hard, right? You guys have done this a millions of times before. This act lasted until someone snuggled up information about you three's true identity to the guards..
