In his previous life, he was a noble king, and she was his beloved queen, but she had no choice but to kill him, whom she also loved deeply.
In this life, he is still a noble king, but she has to atone for the "mistakes" she made in her previous life.
If she was asked to give her all for him again, she would be happy to do so.
No matter human beings, gods, demons or demons, all get out of the way. She won't let him get hurt at all. Take your life as an oath, yes!
