I think the same. I do think the father is the one who turned back time. he is having nightmares of the past so it shows that it actually might be him since Kierra doesnt know anything. And the way he acted in ch.37 also shows that he is changing (maybe due to the nightmares or his feelings for kierra).
That blonde hair wizard that turn back time said that the person who requested in would normally keep their memories but she got it inside. I'm thinking the father was the one who wanted to turn back time and requested for his daughter to get the memories back instead of him. (I mean why else does the father have only fractions of his memories).
Anyways that was just my theory nothing factual!
