Nanaka 6/17

A seventeen-year-old student values her education and future aspirations, often scolding her best friend for his reckless and immature behavior. After an intense disagreement, she accidentally falls down stairs and sustains a head injury that causes her mental state to regress to that of a six-year-old. Her father and the friend she once criticized must now conceal the incident while she attempts to navigate daily life and relearn growing up.
