Misha Miyamoto, 29, lives alone in the house her grandmother left her, has held the same job since high school, and likes her life as is: simple. Unfortunately, her satisfaction disappoints everyone around her. Her boss can't fathom why she won't take a promotion, her lack of ambition dissuades potential love interests, and her parents push her to sell her estate since she has no interest in starting a family. These pressures leave Misha isolated and sick of justifying her choices. When an earnest 18-year-old mistakes Misha for a fellow student, she finds solace in his lack of expectation and begins a relationship with him. But as their relationship grows, so does Misha’s reckless behavior.
