To Walk Beside You (2009)

A 17-year-old country boy named Norio decides his only option is to follow his late parents’ example and commit suicide. After failing even at that, his 34-year-old English teacher Akemi convinces him that he should instead move to Tokyo with her and become a lawyer on her dime. Unfortunately, Akemi doesn’t have quite as much money as she leads Norio to believe, and has to secretly get a job at a karaoke bar under the guise of “going to the salon”. Meanwhile, she continuously prods her somewhat dimwitted student to work harder toward her manufactured goal of him becoming a lawyer. Although Norio is falling in love with Akemi, he’s not all that interested in studying, and matters only get worse when he discovers his benefactor’s secret source of income.
