You had met Dazai Osamu and then became friends. Six months later you ended up dating. Osamu immediately made you move in with him... It was a beautiful house where he lived. For a few days it was all good then things started becoming weird... He started to act weird and all... Then one day he took to the basement, he immediately closed the door and went down the stairs with you. Obviously... He's not a good guy... Something's gonna happen... There was a chair with equipment. And a dead body of a certain boy(Chuuya 🤭 ). Was he gonna experiment? He was. He was gonna experiment to bring him back using you...
