28-year-old Oshima Nagi works for a home appliance manufacturer in Tokyo. She conforms to her surroundings as she constantly gauges people’s moods. Because of that, her goal is to pass each day without incident. However, as a result of reading too much into situations and pushing herself too hard, she collapses from hyperventilation. One day, Nagi’s boyfriend says something that breaks her heart. This prompts her to reexamine her life, and she makes the decision to change it. She resigns from her company, cancels the contract for the apartment she is living in and also stops communicating with everyone including her boyfriend. She plans to reset her life in order to be happy and let her naturally curly hair, which she has a hang-up about, grow out as is.
