A Man in a Veil (2020)

It is also same revenge story but opposite hear the ML takes his revenge instead of FL!
and the story is also similar but not completely if you like this drama you will also like, (A Men in a Veil ).

Both villains Min Jung and Yoo Ra grew up in a poor family and are greedy for wealth/status, and their moms also help them with their lies. Both FLs raises the baby that they abandoned so they could marry a rich guy. The ML in A Man in a Veil is similar to Ji Sang's character, he wants revenge since Yoo Ra caused his mom's death and Min Jung caused JS' dad to die. Min Jung and Yoo Ra blackmails the villain moms with their secrets from the past later on.

Both dramas are addictive with greedy villain FLs and main characters want to get revenge for their loved ones.
Uhm Hyun Kyung was the FL in both dramas and there is a similar plot twist (spoiler)
Kim Hee Jung was also in AMIAV before as a villain but now she is a good supporting character.
