When Kinaho's boyfriend Akito introduced her to Touma and Haruhi, her life underwent a dramatic change. The siblings had sadly lost both their parents in a tragic incident. Previously living on her own, Kinaho decided to welcome them into her home, and thus began their journey of adjusting to living together. They faced a few bewildering days initially, but eventually, the three of them formed a strong bond. Notably, Touma was a studious second-year middle schooler, while Haruhi was just five years old.
