It was a beautiful evening in Yokohama, Japan. Somewhere between the city and expensive houses, is a gorgeous black and white marble mansion. It was designed beautifully, and clearly was expensive. It belonged to two people, Dazai Osamu - one of the ADA’s sharpest detectives and former port mafia executive - and Nakahara Chuuya - Top executive in the Port Mafia. They were married, and living in that mansion together for 6 years now.

They were having a peaceful evening together, both surprisingly had the same day off. Dazai was laying peacefully across the couch, head resting on Chuuya’s lap, she was reading a book, one hand gently scratching his head. Dazai hated his head touch by everyone, everyone except Chuuya, she is the only person he allows it. Dazai was not sleeping, just resting his eyes as he enjoy his wife’s attention. Until a sudden loud bang came from the front door. Someone was banging on their door.
