They end up together.....the MC realised there is no way she can run away, because he always catch her, and one point she realised that suicide is not an option too, because ML just turn back the time. They going zo have 2 child.
From the detailed spoilers there was not a typical redemption arc, and because this pretty much readars was disappointed. He kneeling and appologies many times, but still he says he cannot let her leave, because he need her, what I love in MC, that she constantly bring back the past like:why do you want now this and that, when I wanted it you didn't even bat an eye....in these times ML feels like her words stabbing him....and MC never says out that she love him.
So the novel clear it up: MLs message with the sik scarf to her back then was was either shut up or die. In the novel it was implied that she forced him to make her the the empress and legitimate companion but he didn’t care back then, so he just sent her the scarf as a warning, thinking that MC would choose not kill herself but she did.
So after she died, he suffers from the after effects of vomiting black blood 12x a day for around 2 to 3 years before going mad and killing everyone then turned back time.
