[Machine Translation] Aya Otani, a 31-year-old single woman, is on her way home from a big fight with her date when she walks into her favorite bar. While she is talking with the owner, Mihiro, about her past heartbreak, she is approached by an elderly man drinking in the corner of the counter. The man, who is called "Sensei," tells her that there is another reason for her heartbreak, based on Aya and the other man's words and actions at the time she was rejected. The "reason why I was rejected" and the "truth of my broken heart" that I had assumed. This love mystery depicts the "misunderstandings" that men and women in love fall into, using the hit songs, fads, and social situations of the time.
