My Marriage Is With Your Older Brother summary: Yeojin, who once lived a life everyone envied—married to a handsome news anchor and the heir of a wealthy family—was, in reality, trapped in an unhappy marriage.

She thought it was the end, but when she opened her eyes, she found herself back on the day of her wedding. Watching her husband and his mistress brazenly whispering sweet nothings to each other, Yeojin made a decision: she would do whatever it took to exact her revenge, even if it meant marrying her husband’s older brother.
