あらすじ

One day, the Literature Club lends out its chairs to other clubs, leaving only a single chair behind. Shou and Yuzu are the only two left in the clubroom, and they end up in a lighthearted argument over who should sit in the remaining chair. Each wants the other to take the seat, and neither is willing to back down out of kindness. In the end, Yuzu gets her way, and Shou is forced to sit in the chair alone. Shou feels bad about being the only one sitting... until a sudden idea strikes him.
