After I Won Over the Scumbag, They All Came Crawling Back

[Mutual Firsts + Quick Transmigration + Regretful Exes + Over-the-Top Drama + Satisfying Revenge]

I used to be an ordinary office worker. In my previous life, my boss set me up and my coworkers bullied me, leaving me to live in misery and despair. Then I transmigrated and became bound to a System. In this life, I'm taking back everything that's mine! When my scumbag ex's beloved first love showed up to provoke me, I slapped him across the face. When my ex deliberately gave me the cold shoulder, I went off the rails and made him a trending topic. When he regretted everything and begged me to stay, I hopped on a helicopter and flew off to vacation in North America.

I transmigrate through multiple worlds, and it's pure satisfaction from start to finish!
