A Akaza x Rengoku story. After surviving the battle at the Mugen Train Rengoku was healing at Shinobu's mansion by day and chatting with the demon who nearly killed him by night. Akaza knew he was defying Muzan, he was commiting outright treason to his entire race. But he couldn't really help it, it was hopeless love after all. Requested by @TengenUzuiWife
