Due to family circumstances, I once again found myself living at the Tsukishiro household. There, I reunited with Sumire and Kaede, the close-knit sisters who grew up with me like siblings. What awaited me was an unexpected situation where they both competed, asking, “Do you like ‘Onii-san’ (big brother)?” or “Do you prefer ‘Onii-chan’ (big brother)?” “Which one do you like!?” I found myself in the middle of their dispute, trying to mediate between the two every day!
