Happy People (1997)

An Twilight Zone-ish anthology of three unrelated stories from Japan. First off, a diligent student studying for her college entrance exams is driven crazy (literally) by the noisy neighbors upstairs. Next, a handsome young executive at a small company receives a cryptic note from the eccentric office girl expressing her undying love, and if he doesn't meet her in the parking lot during lunch "she will die". The last story involves a sweet housewife who resorts to unusual measures to get rid of her nasty, bedridden mother-in-law.
