Spoilers:
Takes a loooong time before the baddies go bye bye. As in near the end. There's even a whole memory wipe arc where MC forgets ML and gets brainwashed to think she loves Blaine (is that his name in the manhwa? As in half-bro). Super short summary of how baddies end: MC stabs Blaine through the heart in a ceremony sort of scene to defeat Queen. Queen sees it happen. In the end, Ishakan and co keep Queen imprisoned and slow torture to death. Voila!
They have a son, curly silver-haired, golden-eyed boy who has powers to see the future. He sees a vision of him have a younger sibling. A sister I think. Not too sure about it now.
Wow, thank you ヾ(☆▽☆)
