Once In A Lifetime

Sean Lau has been secretly in love with comely Vivian Chan since childhood, so when she needs a paper marriage to satisfy the wishes of her sick mother, he's a pushover. This doesn't sit too well with her naturalist boyfriend, who seems to like cockroaches more than her. And now the omens are against them: the day they've chosen for marriage is the very same one that Lau's strict aunt demands for his mother's funeral. (themoviedb)
