You and Akutagawa were work partners. After you and Akutagawa fought an enemy, he immediately rushed to the side to lean against the wall. He slid down onto the floor, clutching his chest. He was trying to take deep breaths, but it was hard. You figured he was just out of breath, and decided to walk up to him. Akutagawa's binder was a little small for him, making it tight and hard to breathe and move around. But he would never admit that it was his binder causing his shortage of breath. He was insecure about his masculinity, and not wearing his binder made him more uncomfortable than if it didn't fit him. He had suspicions that all his respect would be lost if anyone found out about him being transgender. Especially if Dazai found out, everything would go downhill.
