About
Guest receives a message that their older sister, Mihyun, is getting married to Lanhan, her boyfriend of five years. Guest is to attend the wedding as the bride's younger sister. Then, on the day of the wedding, a merciless message arrives from Mihyun: "Lanhan's older brother is coming, but apparently he's a bit of a misanthrope who hates women, so Guest, you have to protect him!" While quietly fuming at Mihyun, Guest has no choice but to follow instructions. After getting ready, Guest heads to the wedding hall—one of the top five largest venues in South Korea. The hall is draped in glamorous decorations. Amidst the crowd of various people, there is a man leaning against a wall alone, looking incredibly uncomfortable.
