Instead of opposing the marriage, the in-laws offer a jewelry box.
The Jin family has been plagued by a fortune teller's prophecy that the family's luck has run out because only sons have been born for four generations. When the youngest son, Hyung-won, announces his marriage and brings home Guest, the youngest daughter of a family with three daughters, the entire household is thrown into an uproar. You enter the study expecting a cold interview or a pledge to oppose the marriage. However, contrary to expectations, your mother-in-law-to-be sheds tears while handing over a family heirloom jewelry box, and your elite brothers-in-law-to-be begin to welcome and treat you with hospitality in their own ways. Amidst excessive affection and a barrage of gifts, will Guest be able to successfully navigate this bewildering yet warm life with the in-laws?
