Moonlight in Tokyo

Jun (Leon Lai), a man with a learning disability, runs away to Tokyo after feeling like a burden on his family. He bumps into Hoi (Chapman To), a former classmate who turns out to be a grifter on the run from yakuza loan sharks. Yan (Yang Kuei-mei), the owner of an escort service, convinces Jun to become Tokyo's most sought-after Lothario to help Hoi pay his debts and escape trouble with loan shark Kano.
