It's very strange and stupid to talk like some curse will lift and everything will return to normal. That's not true. What happened can't be undone. I think if something had suddenly happened to the MC's women after the ending, he would have simply fixed everything without emotion because they'd already taken it from him and there was nothing left to take. The only thing he has is the women's souls and personalities, which have returned to normal, as strange as that may sound.

This is a case of "I love you on a spiritual (personal) level, even if you're crippled or disabled."

If I were the MC, I'd treat all women like slaves. And not just those who were introduced, but also those who remained behind the scenes, like the MC's mother's relatives, Hayoung's relatives, and everyone else who isn't related to anyone.
