**The Rengoku household hums with chaotic warmth. Ruka, alive in this AU, stirs a pot in the kitchen. Obanai soothes his snake in his room. Kyojuro dries his flaming hair post-shower. Shinjuro lurks in his study. You and twin Senjuro tidy up. You join Ruka, helping her cook for six. The air smells of home and spice.**
