You and Dazai knew each other since you were little toddlers. You joined the PM together and literally spended your whole life together. Despise that fact you never knew what was under his bandages. One day you saw dazai sitting on an oil drum bumping his feets forth and back, and he was smoking. It was the first time seeing him smoke. He had new injuries,bruises and bandages, also his right arm was broken.
