The spoiler said lucius has 3 wives and had children with the first wife and Pauliana marr...

Wow. You added a spoiler and got most of it wrong.
1.) He did have 3 wives. But in the end all three of them were ou of the picture. One died, one got arrested and one filed for divorce. Pauliana were on good terms with them and made them realize that marriage isn't the only thing that women are supposed to do. They cherish her quite well too.
2.) Pauliana didn't marry anyone except Luxor. She was only engaged but found out the guy was scum so I guess you can imagine what happens to him in the end. They had their happy ending and they have a son together.

Where did you find the whole story?

so the novel is finished? and they never marry each other? (but still have a happy ending?) I regret scrolling down and seeing this top post so much lol
OP PLEASE PUT SPOILER WARNING RIP

They did marry each other. Luxor=Lucius. That's the name of the Emperor/Male Lead if you didn't know.

Wow, thanks for that spoiler. Mark it next time.

aaaaaah tyyyy i didn't know he went by luxor, too, lol

It's a translation problem. Some use Luxor while others use Lucius.
I think Luxor sounds better tho

So at the end, she will end up with the King? So, it's alright for me. Thanks for the spoiler. Hahhaha...

Addtion...If they are not end up together, I feel so frustrated. I think it's normal lucius had 3 wives. It's look more real. Maybe the journey of him to be a King make him wed 3 woman.

Thanks a lot for the explanation.

Where can I read the novel?

Next time do this please

USE THE ENTER BUTTON OKAY just a tip （/TДT)/ don't spray it just hide it

Yeah...where I can read the novel. Novel updates just had one chapter. Even the original novel, I did not know where the source it is.

So in total, Lucius had two son?

The first child was a princess. The second child (with Pauliana) was a prince.
The first child became the heir to the throne. She was much like a leader. Beautiful, shrewd and extremely intelligent. Luxor/Lucius had to change the laws so that a woman could inherit his throne. Another feminist move. Love it.
His child with Pauliana chose not to inherit the throne but instead protect the new heir, the princess. He's really strong and adept with the sword, even Sir Aino was awed by him. Considering both his parents weren't that well off in combat, it actually came as a surprise

Ohh...thanks a lot. Very appreciate it explaination. The spoiler helps me to prepared my heart even though the thing not going the way I want. Hahaha... But it's look like this manhwa had long journey. I do not know but my heart hurt when I heard this. But it's alright. Means, he loves his children & there is still happy ending there. Unfortunately the first empress die. If not, Paulina will be the 2nd wife that will stay with Lucius. Hahaha...so it will break my heart if that happen. So glad that story become like that. Did Lucius had affection feeling with 1st empress or he did that to get a heir?

It's good to heard about the siblings helps each other.

One more question. Hope u are alright to answer. Did Lucius get jealous when he know Paulina enggaged with other guy? Becoz spoiler said he love Paulina. Even I know the spoiler I still read this manhwa. I just want to fulfill my curiosity.

No, he only loved Pauliana.
In fact, I am not entirely sure if the first child is really his. The namuwiki spoilers mentioned a prince impregnated her. Call me crazy, but Luxor was no longer a prince when he married her. He was the emperor. So this is a blank spot to me too. I haven't read the actual novel.
Also, Luxor/Lucius and Pauliana's child didn't inherit the royal surname, he used his mother's surname instead. Winter. His name is Jared Winter

Ohh...it's okay. Thank you very much. But...it is just my thinking. If what you said is true the princess is not his so what purpose he become the emperor and at the end his throne & wealth become others? But we will know it later. It's okay. But I do think that the mahnwa/novel had their purpose, maybe to show off the feminism ideology like what u said before.

It's obviously, the prince take the surname of his mother(Paulina) because most of child that grew up by his mother will take his mother surname. Maybe It happens when Paulina flew away from the country and the child grew up without father. I don't know. Furthermore, the surname can be change but some child do not want change when they independence and adult. Becoz they can thinking and appreciate the their identity & origin.
