She was a person who killed people for revenge. She gave up love and family affection for revenge, but still couldn't let go of them. Only when she got her revenge did she discover what happiness was, but family feud must be avenged. She made a choice between giving up and gaining.
He was an indifferent person, but for her, he did everything she asked him to do, and there were many things he wanted to do for her, just so that she could be happy. I don't know whether the result is joy or sadness.
He is a person who has been waiting hard. Ten years of waiting has brought about both joy and sorrow, but he has no regrets because he and his lover finally meet again. But whether meeting each other is joy, maybe it is also sadness.
What disputes will there be between the three of them, and what will be the outcome? I wonder if it was him who fulfilled him, or he saved them, or maybe she let go of everything just to prevent them from being sad?
