7th Time Loop: The Villainess Enjoys a Carefree Life Married to Her Worst Enemy! Vol 1

From the Seven Seas Entertainment edition

Reincarnation drama gets sent into overdrive in this tale full of romance and scheming--and don’t miss the original light novels, also from Seven Seas! Every time Rishe turns twenty, she dies and is reincarnated to the day she gets dumped. She has been a merchant, an apothecary, and even a maid. For her seventh life, she has one goal: to live a long and lazy life. But then she gets a marriage proposal from the Crown Prince–the man who killed her in her previous life as a knight. Despite her determination to avoid drama, here she goes again!
