So I don’t exactly remember which tale it was, but a princess one. Maybe sleeping beauty or snow white?
The princess wakes up in a modern era, her kingdom is gone. By chance an actor or model (not sure again) finds her and she starts to stay at his home. After a few chapters it is revealed that the evil witch is still alive too, and she is the mother of him. Then she escapes, her guard finds her, etc. etc.
I’ll be grateful if anyone knows it.

Sweety Gem?

That’s it, thank you so much
