My Darling, My Goddess 1982 on netflix

Kok is a bored valet driver who spends most of his day dreaming about the beautiful bikini-clad woman whose picture he has taped up to his office wall. One day, a major crime boss keels over dead in the brothel run by his mother. Trying to keep the whole thing quiet before the guy’s underling return to pick him up, Kok’s mother stuffs the corpse into the box and stashes it in Kok’s parking lot. When the thugs put the squeeze on mom, she claims that she dumped the corpse in the harbor, which inevitably leads to even more hilarious complications.
