Plot

40-year-old Jimmy is growing up, or at least he's getting older. While mooching the upper bunk of his ten-year-old nephew's bed, he enjoys the never-ending generosity of his sister Aiko, and dodges the wrath of his impatient brother-in-law Tak. He thinks that if only he could get married all his problems would be solved. But when he falls head over heels for Tak's niece things only go from bad to worse.
