Sae is Boku's ex-girlfriend from high school. She was a year behind him, and has always called him senpai. On his graduation day, Boku gave her one of the buttons from his uniform. Sadly, he lost touch with her and did not see her since. Our protagonist meets Sae once more on a random day at cram school. At first he doesn't recognize her, but soon remembers when she recognizes him. As it turns out, Sae didn't do well on her entrance exams, so she is preparing to take them again the following year. Upon finding out that Boku is also a ronin, she makes a promise with him that they'll get into college together. When the staff realizes they really need a scenario writer for "Ai kawarazu na boku", our protagonist decides to ask her to contribute (knowing of her little hobby for blogging and fanfic writing), and she hesitantly agrees.
