I like romantic comedies. However, romance doesn't develop like that in reality. There was once a time where I thought that. Encountering a girl who fell from the sky, my school life changes with a clang.

The story centers around Kanade Amakusa, a boy cursed with the mental power of "absolute multiple-choice"—a multiple-choice quiz will suddenly appear in his mind, and the choice he makes will become his reality. For example, he would have to choose between going nude from the waist up or the waist down in school. While in school, he is given another choice: 1) A beautiful girl will fall before him. 2) he will fall from the rooftop in female clothes. He chooses option 1, and a blonde girl named Chocolat falls before him.

The story follows Kiyozumi Kurokawa, a novice editor who is assigned to the editorial department of S ("Sandal") Bunko, which publishes light novels. Kiyozumi is determined to publish a million-selling hit series, but this task is easier said than done when his writers include a genius high school girl and an office lady whose last two series tanked.
