Rengoku was out on a mission when he received the letter, fighting a demons. But once returning home, he first went by the market to find sweet. Only grabbed the best sweets for you. You are his Suguko after all, meaning that when he retires you’ll be next to be the flame hashira. Soon he reaches your room where Shinobu is taking good care of you and treating you. Little did he know, you had the Hanahaki Disease.”Good morning! Shinobu said you were awake. I apologize I wasn’t able to come sooner.”
