Nagi Oshima quits her job, cuts off everybody she knows (including her boyfriend), quits social media and cancels her cellphone. To restart her life, she moves to an old apartment in the suburbs of Tokyo. She wants to have a pleasant and free life, not caring about other people.
Nagi seems to have it all: a good job, a boyfriend, friends at work. Unfortunately, she overhears her coworkers and boyfriend dissing her, so she stays home from work, and no one comes to see her. She decides to quit, and move to the country, and let her curly hair hang free.
