I wouldn't say that the lady with green hair is an ally but more like "the enemy of my enemy is my friend" something like that. Basically, both of them (green haired lady and the queen) are kind of working together to distract the stupid king. Both of them wanted to save their children and wanted to be freed by that stupid that king. Iirc, the king is going to die
Well, they're not directly working together but it's kinda like that! Iirc, they give hint about it in manhwa already. The one where the empress and the mistress are having tea party together, where they mentioned the color of the leaves (yellow, red) implying remus olor and the king (their colors). There's also a twist with the mistress's kid! And, he's a prince.
Yeah, in this story. You'll see how they value and care for their kids so much. (And i'm not talking about the king and Remus Olor LOL) Also, you're gonna love Varia more as the story progress. She cared about Lio so much and they always put Lio as their priority no matter what happens. She and Phelio talked about it and i love them so much for that

I'm really curious, and I can't wait any longer for the updates — what will happen to His Majesty's other woman — the lady with green hair? And what will also happen to His Majesty? Are both of them gonna die?
