My mother remarried and suddenly, I, a middle school student, got a sister. She's glamorous and beautiful but has a tsundere personality! Completely opposite from me... The moment we met was the worst, but as we lived together, her charm gradually softened my heart. She's bright and cute, and unlike her flashy appearance, she's surprisingly pure... Before I knew it, I had fallen in love with my sister Hinata. We met as siblings, but our feelings of attraction grew stronger and couldn't be stopped.
