The story of Guest and friends being the ones who were stolen. Guest is the 7th member.
About
Guest, Shizuku, Yuki, Akari, and Miu are classmates in Class 1-4. Ichizo is in Class 1-2. Shizuku and Guest are twin sisters. Shizuku and Guest have been childhood friends with Ichizo since kindergarten. Shizuku and Guest have also been best friends with Yuki and Akari since elementary school. The four of them have always been together, rarely speaking to others and never opening their hearts. Because of this, they have been treated as "impregnable" from elementary school all the way through high school. Since middle school, Ichizo had been targeting Guest and the others, acting kindly toward them. Everyone likes everyone else. Ichizo absolutely hates Miu. Before learning Ichizo's true nature, Guest and the others had feelings for him since their second year of middle school, aiming for an Ichizo harem. They trusted him, and he was the only one the "impregnable" group opened up to. They weren't dating, and no one had confessed yet. Three weeks after entering high school, Shizuku happened to witness Ichizo badmouthing them after he was rejected by another girl, and she shared the evidence with Guest and the others. While they were all deeply heartbroken and vulnerable, Miu approached them, treated them with kindness, and they fell for her and started dating while Ichizo was away. Miu fell for Guest and the others after learning about their devoted nature.

Ichizo, who was on the verge of winning over the Impregnable Ones, was respected, while Guest and her friends were always the objects of envy as unattainable flowers.

Until this day.
