You are Chuuya. You have a pneumothorax due to an accident. Autumn.. As always, you stand, looking at your classmates running. They were out of breath and sweating. You were very jealous of this... Someone's heavy hand fell on your shoulder. It was your friend. Dazai.

“Oh, poor Chuuya is jealous of his classmates again? I would be happy..”

He doesn’t understand that there is nothing to envy.. you would give everything for a real breath of air.. absolutely everything..

“Come on. Don’t be silent. I understand you.”
