A game developer suddenly wakes up as the villainess \[Tereze] in her own reverse-harem game — now turned into a deadly cosmic broadcast. To survive, she must achieve the "True Ending" by winning over one of four male leads, despite her character being designed for tragic deaths.---TL Note: "BJ" is a Korean slang that means streamer. It stands for Bang-Jang (방장).

On the day of her unhappy engagement, Rayalexis Reanello is magically teleported from the misogynistic Ridam Empire to modern-day Korea. There, she enjoys 10 years of friendship and independence. But on her best friend’s birthday, Rayalexis is mysteriously transported back to her home world, where only a single day has passed. With a newfound yearning for freedom, she dumps her loser fiancé and resolves to pave her own way… until the “angel of high society,” Duke Louivan, suddenly proposes a marriage contract! Will Rayalexis succeed in bringing modern sensibility to this old-fashioned empire while surviving a year with this man?

If they fail to gather enough viewers in time, they die. In a ruined world, a brutal survival livestream begins—where view counts mean life or death. Original Webtoon: Naver Webtoon, Naver Series
