Pretty much the daily drama version of this. FL starts living a false life and falls into a web of lies in both dramas. The more she lies and pursues status, the more her life spirals out of control. The FL in A Graceful Liar is more of anti-heroine, while the FL in Anna seems a bit more villainous.
Both dramas have morally grey characters, a villainous female lead, a heavy focus on the entertainment industry, and they also both explore how far one would go to achieve their own ambitions/desires.
FL lies and schemes her way into the elite. ML is mostly unaware. Lots of secrets, lies, and hidden connections everywhere. EVERYBODY LIES. There's a tonal shift in the second half where everything unravels and falls apart (and everyone rediscovers themselves... maybe? ?)
What I call a "twin swap revenge drama". In Wife Returns, the poor, good twin disappears and the rich, cold-hearted twin takes her place for revenge. In this drama, it's the opposite, both events happen because of the villainous 2nd female lead.
Two MLs got their faces swapped and their fates changed as a result. Similar to how the two FLs in Ruby Ring got their faces swapped and their fates changed.
Both FLs are villains who would do anything to satisfy their ambition and their hunger for power. However, they're both extremely complex too, with tragic backstories explaining their motivations.
Same screenwriter, villainous FL, mostly morally grey characters and one of the main stories revolve around a big conglomerate/chaebol. Plot twists in nearly every episode.
FL becomes a villain due to trauma/abuse. Both FLs manipulate and use people, and while they're ruthless, you also can't help but somehow root for them or sympathize with them. Both dramas also have an ML that's taking them down or planning to do so. And both FLs in the drama go to poor-to-rich and climb to power selfishly.
FL is a villain/becomes a villain to seek power. Ruthlessly ambitious, kills anyone who gets in her way, and manipulates people. There's also a revenge plot in both dramas.
FL is a villain/becomes a villain to seek power. Ruthlessly ambitious, kills anyone who gets in her way, and manipulates people. Both were also adapted from a webtoon.
In both shows, the daughter is getting revenge on her biological mother for abandoning her. The FL is grey/an anti-heroine in both dramas, but the FL in A Graceful Liar is far more villainous.
The FL is ruthless and will do anything to get to and stay at the top. Both FLs are ruthless and extremely manipulative, as well as cold-hearted. Most of the characters in both shows are morally grey.
