Unusual Love Triangle

Two wedding guests arrive on a space station in the not-too-distant future, and the older one tells the younger one a story about the groom's father, who was a well-known entertainer, and his selfish wife. The story begins in Seoul in 2002 - a strange love triangle between a comedian who never smiles, a taekwondo coach and a woman who wants to be a TV star but doesn't do anything to escape poverty.
