On the day Tang Chi won the MMA title bout, she was dumped by her younger boyfriend because his mother was afraid of her bullying him. Depressed, she passed out drunk at a KTV and woke up to find herself transmigrated into another body from two years earlier. Now she's the newlywed wife Gu Linzheng, the heir to the richest family in the city. But she was told that it was only a contract marriage and they'll be divorced after one year! One year to seduce the cold-hearted heir, or try to become a champion fighter again? She'll do both, of course!
