Intellectually impaired he might be, Jun is only dumb but not silly. Abandoned by his family on a trip to Tokyo with only a few notes in his pocket, he thinks he has found his guardian angel when he bumps into a former classmate, Hoi. But Hoi is no angel at all. He is just a grifter on the run from yakuza loan sharks. When Yan, the owner of an escort service, is convinced the ingenuous Jun will make a perfect gigolo, Hoi decides to transform his pal into Tokyo’s most sought-after Lothario in order to eke out a living and to pay his debts. Together the odd couple thus embark on a hilarious adventure, or misadventure so to speak, worming their way into the hearts of desperate housewives and office ladies in Japan. Though Hoi constantly takes advantage of Jun in every possible way, Jun’s generosity and unquestionable trust gradually changes his cynical view of life. A magical bond soon develops between them, sealing their destiny in the most mysterious way.
