Latest33-year-old Akiyama Satomi is a history teacher at the prestigious all-girls high school she once attended. She has earned the nickname "ohitorisama" (meaning "one person") for her perfectionism and capability to handle any work by herself. At the same time, the name also refers to her lack of romance. One day, a young man named Shinichi arrives at the school as a temporary instructor. He's ten years younger than Satomi, has only worked part-time jobs, and has neither money nor status. Although the other female teachers and students find him cute, he is completely not Satomi's type... or is he? Will love blossom between this unlikely pair?

Trivia, insights & behind the scenes
The term 'ohitorisama' became a buzzword in late-2000s Japan, celebrating unmarried women who dine and travel alone — this series both embraces and complicates that independence.
Arisa Mizuki was 31 playing 33, while Teppei Koike was 23 playing 23 — the real age gap is smaller than the characters', making their chemistry oddly more plausible.
