I honestly hope the MC will continue in the same route and end-up with the prince. It looks like she really loved him in the past, she can just confess to him who she really is in secret, and he’ll be her supporter.
@Binary10011 Because the real daughter had a threat on her life, so they want Elena to act as a body double until the real girl wakes up and takes back her place. It's just that it didn't happen until after Elena had married the Prince and had a child with him.
At first it gives Aria vibes, but then she's not actually a villain or act as villain, she's more like Iris with another tragic-naive girl being used in their first life then wants to revenge the one trash family.
About the ML, but i hope it's not the crown prince, he seems like an ass too towards FL, i hope FL is capable to stand alone.
