Her baby brother is cute but I feel sad for her Mom. I hope there's relationship progress.

NOPE.

If the spoiler right, you don't want that to happen.

What about her lil brother?

I'm not really sure about the brother.
I'm talking about the mom. In the first life, she's the one who sold FL to the emperor. And in this timeline too, she's gonna do the same to FL.
So no, I don't want to see them reconcile.
