This is a bad situation for the emperor but it's good that he didn't cause a fuss. I hope they can have a better relationship in the future. Nothing can happen until the empress is dealt with. In the pass he wasn't allowed to be with her due to the empress's schemes. Also the fl is heart broken from that time since they didn't believe her. Which is understandable being she had no proof she was his daughter only showing up 20 years later without spirit power. Hopefully this time reversal can save them too.
Love is love
