Chiisakute Kawaii Bungei-bu no Chitekina Senpai wo, Hiza no Ue ni Nosetara Mainichi Suwatte kuru You ni Natta

小さくて可愛い文芸部の知的な先輩を、膝の上に乗せたら毎日座ってくるようになった

by Yumeigetsu, Ame Kanro

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. “If I’m sitting in the chair, then I can become the chair and let Senpai Yuzu sit on my lap, right?” Or so he thinks.
