Major Spoiler (Only read if you very curious)

Guys.
So, this isn't regression but multiverse / split timeline.

Leoni jumped from 1 timeline to other timeline.
The 1st world is still exist even until now, but Leoni on that world already moved to 2nd world (current world).

Rudger / 8th Prince, in 1st world, loved Leoni. But he was a stutter, he was afraid talking to Leoni, embarrassing himself, and made Leoni hate him. Leoni is smart and grace. Leoni was raised with a lot of education so she can be married to highest bidder (yeah the duke was shitty). That's why Rudger really felt inferior to Leoni. And only talk very little and necessary. Leoni thought Rudger hated her. Such stupid misunderstanding because inferiority complex. Rudger put his nanny as leoni maid not because he wanted to bully leoni, but because nanny was suspicious person, so he wanted to surveillance her. It's Rudger fault tho, putting someone so ugly inside beside leoni. When Leoni got mad at the nanny (Leoni missed her child), nanny tattled on Rudger. Actually Rudger finally getting rid of her.
Rudger wanted Leoni to be proud of himself, so he joined the war to raise his status. He came back as winner and was about to crown as crown prince. But he found out late that Leoni was imprisoned. Leoni only saw glimpe of Rudger shouting her name when she was moving to another world (2nd world). At that time, Rudger believe Leoni actually have mystical power from her family which can travel time & space. He also preserve Leoni dress that have her painting (where Leoni disappeared into).

Duke & Sherin were stupid bunch, he thought he could just replace Leoni with his favorite daughter, Sherin. But Rudger was in grief, he cut the duke arm, and scared Sherin face. He later sold both of them to the duke of the North. Duke of the North is mad scientist who hates the duke (this mad scientist loved Leoni mom a lot). So this mad scientist used duke and sherin as experiment and they both died miserably.

About the mage, Leoni 2nd husband. This is also stupid misunderstanding made by that bitch Sherin. Sherin is actually very far distant relative of Leoni maternal family. She has little brainwashing power. This power only works IF the opponent is weak minded (depressed person or sad person), or IF apply continuously, like when she brainwashed the duke to love her. In this case. The mage is actually loved Leoni (just like Rudger). But Leoni kept refusing him due to her grief losing the crown prince. They do have kid, and she loved her kid very much, and so far her new 2md husband is kind to her and also love their child. So leoni open her heart to him. Before Leoni open her heart tho, the mage was kinda depressed and sad that Leoni never loved him back even tho they already have child. This is the bitch Sherin came in. She actually jealous over Leoni having a loving husband, he also handsome and rich. So Sherin wanted him for herself. She started brainwashed the wizard, she kept telling lies Leoni have love affair outside their marriage. Which grief the wizard. When the brainwashed fully overtaken him, the wizard disappeared with their child. Sherin was taken aback. Instead coming to her, the wizard chose to ran away. But at least Leoni is not happy anymore.
The wizard went to the noth and met the duke of north. Because the wizard is genius, the duke made him do a lot of experiment. But later, the wizard heard news, Leoni was crazy over losing her husband and child. So he finally realized his stupidity. His wife actually cared for him. He wanted to go back to Leoni. But the crazy mad scientist imprisonment both wizard and the child. After sometime, they both escaped. But the mad scientist kept pursuing them. Oh, the duke of north has this scary power of death or something I don't remember. The wizard felt like they both could die. So he used his magic and every last drop of his mana power to "froze" the child. It's some kind protective barrier that froze the time. And can only be lifted by him, the wizard. But because he used up all his power, he was easily overpowered by the crazy guy and died. Unknown to Leoni and everyone else in the world.

Rudger in 1st world wants Leoni to comeback, so he looked for Leoni 1st child, and found him froze in magical barrier. But he kept the child, hoping Leoni will come and stay with him again for the sake of her child. After Rudger became the emperor, he also fixed his jaw, so that's why he didn't stutter again.


Leoni, ML, and 2nd world wizard do visit Rudger in 1st world. They first unfreeze the child. Bit Leoni chose to stay in 2nd world and marry current Rudger and have a kid. 1st world & 2nd world both visit each other. 1st world Rudger finally able to see his child who was born in 2nd world. And Leoni can also meet her 1st child who stay with 1st world Rudger.

But tbh, 1st world is a mess. The world kept continuing, but the child lost his mother, and rudger lost his wife. While 2nd world is safe and sound.

There's more to it about Leoni dad. He got a good ending tho. So you may prepare a table to flip when you angry about it. Sherin will not change to the better. Leoni have good sibling relationship with crown prince. The current wizard will also got brainwashed but he realized sooner, he only wanted to know his lingering feeling towards Leoni which doesn't make sense, because they only in work relationship (not even friends). But when he realized he was brainwashed to brought Leoni to her grave, he snapped out of it and told Leoni it's dangerous.

Tbh. He is the only wizard. He live sooo long. He is a genius, rich, etc, but he easily got brainwashed. It's annoying plot. I understand the 1st time. But 2nd time is weird. I think his punishment was to never appear in front of Leoni again, and to be selfless and do good deeds by helping people all over the world. So he has to keep going to help people in need.
