very similar, im shocked no ones recommended it. FL lost parents and was raised by bad relatives, she meets an influential women when shes a kid, lady sees her mistreatment and wants to adopt her but loses her memory before she can and the adoption falls through. Fast forward to future, lady starts regaining some memory and wants to see the FL, but the FL's horrible aunt/foster mother lies to the lady and makes her think that the girl she was gonna adopt was actually the FL cousin/aunts daughter, with the intention of getting money. The FL's are very similar and she also meets the ML the same way as in shining inheritance, like at the airport with a mix up, and the ML in both shows are nepo babies.
They are similar in a lot of ways, and it has that classic early 2000 kdrama vibe. Also the FL's are the same actress
