Who is Louie again, I was reading chapter 115 and I can’t remember who that man is

I think the prince empress liza's son

Yeah he’s Liza’s son

Is he always had a white/purple hair? I think his hair colour is similar to the empress. Isn't it odd he had that colour when he had a blond/red haired parents?

He has like a light brown color, I think it’s just to hammer in the fact that he’s more plain or ordinary compared to Ian lol
