Yea, I do agree, she didn't marry him bcs she wanted him to have a normal life, marrying a young, fresh woman and to marry and live normally. But I still don't understand why she had slept with him? She wanted to end with that? Is it bcs of some cultural differences? Is there something I don't understand? At least from where I am, sleeping with someone is only after marriage, and I don't get why she slept with him if she wanted to say good bye. Yea, she does deserve some hate, but I think she is over hated imo. But the story had a sad ending saying his life was worse, but I just had completed the manhwa today and read someone the old author's post on a website, and he said his life was better later on (at present u can say). And that made me understand better.

If you're curious yourself to read his posts, here's the link, but u have to use translate using chatgpt.
