He is the one who turned back time definitely. And also the one who knows the truth of her's ability.
I don’t know anything but I am pretty sure it’s the protags mother. We know that she has relations to magic and if you pay attention to her hair...
Its a good theory...... there is a huge possibility....but doesn't she love her daughter at all?
She hasn’t actually met her daughter yet. Plus we know that the jewels that the auction gets are from the mysterious hooded person. The last jewel was her mother’s brooch. Her mother may not know that her daughter married the duke instead. Also she did literally rewind time itself to do whatever she is doing, so I don’t doubt that they may have the conviction to go against their daughter.
arghhhh im still anxious about that mysterious dude who approached her cousin and ex fiance
