When Geu Roo's father dies, Geu Roo's guardianship passes to his uncle, ex-convict Cho Sang Gu, who is a martial arts fighter in underground matches. Per the father's will, Sang Gu must care for and work with Geu Roo in “Move To Heaven” for three months to gain full guardianship and claim the inheritance.
