Can you help me find a specific manhwa/webtoon

It's about the fl going back in time i think and she's facing her sister who steals first her childhood crush then her boyfriend then her fiancee and the sister has a bracelet that lets her see the percentages of the love interest and she can manipulate them. And I remember the fl is doing a perfume business and her sister tried to set on fire the perfume creator so that she can overthrow her business
