This was gotten from someone else post so credits belong there... the spoiler was too long so I just copied and paste Cr: Guide1410 Other spoilers can be found here https://forum.novelupdates.com/threads/father-i-don%E2%80%99t-want-to-get-married-%EC%95%84%EB%B9%A0-%EB%82%98-%EC%9D%B4-%EA%B2%B0%ED%98%BC-%EC%95%88-%ED%95%A0%EB%9E%98%EC%9A%94.108100/

His backstory is that since he was young he was very strong and takes the Knight Commander’s title when he was young and all.
The emperor is very greedy and he wanted to use Regis (The father’s name). one time the emperor will ask him to share a drink with him, Regis was underage but couldn’t really refuse the emperor so they had a drink and when Regis was drunk the emperor will ask him for a favor and Regis just says yes because he can't refuse him and unknowingly when he said ‘yes’ he was actually swearing an oath that he couldn’t break unwillingly. When Regis found out it was too late. the truth behind the oath was the emperor’s ring. with the permission of a side, they can’t disobey the ruler of the ring. the ring only obeyed a person with the most mana, that’s why the emperor killed most of the magicians and wizards and collected their mana so he can be the person with most mana, that’s the reason that there is no tower of magicians and there’s not much wizards. so the emperor got Regis’s permission when Regis was careless and after that when he gave a order with the ring, Regis couldn’t disobey it.
Emperor used Regis to kill all his enemies and people he wanted dead.
So later when Regis succeeded the Duke’s title from his father, he went in political marriage with our MC Juvel (a nickname for juvellian)’s mother. The mother’s name was Amelia. so after Juvel’s birth, Regis was busy most of the time and didn’t even come back home at the nights. because of that the mother, Amelia was depressed and thought Regis is cheating on her and doesn’t want her and they’re daughter anymore. which was not true at all, whenever Regis was home he played with Juvel and spoiled her. they were really sweet. there was actually a reason that he wasn’t home most of the time at nights. The Floyen dukes had some responsibility to check a sealed place from time to time, the first emperor of +100 years ago was sealed there. so regis will go to check to make sure that everything is sealed and realized that someone is there, and it’s actually the sealed emperor, Phanphil (which had a backstory of his own). he was immortal or something because of magic? and he wasn’t physically there because he was sealed. but he tried to manipulate Regis to break his seal but Regis refused. but regis just couldn’t leave it alone because it could manipulate other to break his seal and so regis went to check on Phanphil every night, or from time to time(?). the other reason that regis wasn’t home often was because the emperor would use the ring on him and order him to kill enemies for him. anyway because of this Amelia thought he’s cheating and they argues from time to time. some times Regis would come after he was used by the ring, and amelia would sense that something is different about him. there is one time that emperor orders Regis to bring his weakness to him and Regis’s weakness is his daughter, Juvellian. so his body moves on its own and he goes to the duchy to take juvellian to the emperor. the emperor wanted to threaten Regis with his weakness. The emperor had some inferiority complexes and despised Regis. Amelia senses something strange and tells Juvellian to hide. And when regis comes for juvel she senses that there is something wrong with him and stops him and asks who he is, when they start arguing Juvel comes out from the place she was hiding and goes to call for servants to stop her fighting parents. but the servants ignore her and something seemed wrong. when she goes back she sees her mother’s dead body and amelia’s last words were that she shouldn’t be scared she also sees Regis soaked with blood and some servants dead bodies there. and Regis starts crying very very sadly and horribly. the small juvel thinks that her father killed her mother, and is horrified of him. on her mother’s funeral when she sees Regis she immediately screams in fear and faints and after that this happened whenever she met him. Regis can’t bear hurting her so he goes to phanphil and says that if phanphil erases Juvellian’s memory with magic he will open half of his seal. so just like that phanphil erases juvel’s memories and juvellian has no memories of her early childhood. Phanphil’s seal is not still completely open so he still can’t have a physical figure. after that Regis avoids Juvellian because he doesn’t want to hurt her. but he always loved her and wanted her happiness. the reason regis didn’t show up on her party in 1st timeline was because that day he was being controlled by the ring of the emperor. when Juvellian suddenly is lovers with Mikhail (the trash ex boyfriend of mc and original male lead of the novel) the only reason Regis was nice to him and favored him was because he was juvel’s lover and he wanted her to be happy. when Juvel was accused of poisoning the princess, of course Regis without hesitation knew that she wouldn’t do such a thing and that the emperor sill use this chance to get rid of his daughter, so he took him to the prison because it was a safe place for her and even gave her one of his greatest swords that had magic which would protect her. after that he begged his disciple, the crown prince and the ML, Max to go and protect her daughter. he was always neutral to the succession of the throne and didn’t agree to rebel with the crown prince for the throne. but because of his daughter, he promised max that he would rebel with him and help him in the succession of the throne if her saves his daughter. that’s the reason max visited juvel on the prison that day, but juvel who misunderstood everything killed herself.
after that Regis went crazy and killed everyone and destroyed everything, the emperor tried to use the ring on him to stop him but because his mental state was crazy it didn’t work on regis and he killed him too. later it showed how Regis looked at the crown and said that it doesn’t mean anything if it’s not Juvellian who is wearing it.
when later juvellian remembered her memories, she understood that it wasn’t her father who killed her mother, but it was the servants that were actually assassins from the emperor. that’s why they ignored her when she asked for their help.
so in current timeline, Regis gets a nightmare of the 1st timeline and remembers what happened then.
it was really sad that Juvellian had so many misunderstandings about him when he only wanted her happiness.
some sad stuff are that, Regis always thought about her and even referred to her by her nickname ‘juvel’ or ‘my juvel’ in his heart, he also stalked her sometimes.
the reason she went to look for marriage candidates after hearing her type, was that he misunderstood that juvel wants marriage and he wanted her happiness so he was looking for best people.
so fortunately this time their relationship slowly heals and juvel will get her memories in somewhere in

Ok I can't wait anymore...Spoile me !

(Post from novelupdates)

I remember reading the novel way back, and there are alot of dirty witty jokes about the emperor’s stamina in bed etc. lol but the most memorable scene was when the Empress & Emperor finally confessed their feelings and was acting lovey dovey when suddenly there was a messenger saying concubine Lin had an illness and the Emperor had to leave...

Then just before the ML left for Lin’s place, the MC asked him to stay with her because she just had this feeling that something bad was going to happen  though the ML still left the empress to see Lin but Lin was all fine, just wanted to eat something together lol so the ML asked Lin did you fake the illness you never did this before etc. While they were still talking and taking their sweet time together a messenger came rushing and told the empress was kidnapped from her place by some assassins...

Then the emperor rushes to the MC’s palace, only to see everything in disarray and calls for a horse to go look for her while everyone was discouraging him saying it was dangerous. He goes after the empress and finally finds her but she is bleeding and he was crying and shaking her body really hard repeating “Empress wake up/say something...” and he loses MC to the assassins somehow again (? I don’t really remember the details) and he cries hard recalling the MC’s last words “can’t you stay with me because I have a bad feeling something bad is going to happen”

The MC was nowhere to be found for 2 years and during that time the ML turns into tyrannical king and everyone says it is due to the death of the empress. The ML finally fell in love with her, only to lose the MC so quickly afterwards so he was devastated. She comes back after 2 years with a new identity and in the end, they end up together.

(And this one was the one that was already posted here)

After the empress’ death, the MC goes back to her original body (she actually knew she had to leave the empress’ body that day but so she asked the emperor to stay with her which became a huge trauma to the ML) and after two years she goes back to the palace disguised as a male escort/bodyguard due to political shenanigans. The MC was actually summoned for a reason, and it involves this radical group founded by the Ryeokuk’s royals who wants to assasinate the emperor.

MC felt somewhat attached to the group though she enters the imperial palace and wants to protect the emperor seeing how the ML blames himself hard for everything and turned into someone completely different. The ML also left the empress’ place exactly as it was before, and gave out harsh punishments for everything involving the ‘late’ empress. The story kind of turns into a ‘BL’ romance as naturally the ML is reminded of his one true love-the empress from the MC’s expressions/habits when she starts working as the emperor’s escort and falls in love. ML admits his feeling for the new MC pretty early on, even though he is a ‘male’ escort/bodyguard, because he really regretted losing the empress without admitting his feelings. The ML even gets jealous saying you should be my man even in front of beautiful women lol and that causes Gong Lin to panic again and she tries the frame the MC, and even going as far as recreating the bloody ML’s trauma by harming herself and then copying the last words of the empress to hold onto the ML (which is pretty messed up imo).

MC felt angry about that incident and tried to tell him the truth, asking what if the empress is not dead but just hiding herself due to circumstances...but the ML reacted pretty voilently and storms out to go see his concubine. MC was disappointed because it reminded her of her last day - even when it is extremely important, he always chooses Gong Lin. So MC starts acting cold to the ML, refusing the snacks he orders for her, not meeting his eyes, and trying to avoid eating together etc. ML was scared that he hurt the MC, and he didn’t want to lose ‘him’ too so he asked why he was mad and he will try to fix whatever it is which surprised MC since he would have never done this before with the empress. ML even confesses that he is in an unrequited love with him in front of everyone, and tries his best.

That’s why when it was revealed MC is part of the infamous group that abducted the empress, it hurt him pretty bad as he thought she approached him on purpose and how he really fell in love with the person who killed the one he loved the most. While in prison, she tries to say she was trying to protect the emperor all along, but the ML was very conflicted with his guilt for the empress. Then when MC is alone with Hoon, she confesses her real identity considering her group obviously abandoned her and left her to die, and to prove it she recounts how they met the first time, with the intruder and the stone... The prison guard listening their conversation was member of the group, so the guard murders the MC while Hoon and the emperor was on their way to the prison. ML sees another bloody gory dead MC, a repeat of his worst nightmare, is shook to the core for the second time.

Fortunately, MC goes back to the empress’ body and a lot of political stuff about this prophecy about her and how she will rid of this group from Ryeokuk. She is given three choices including one where she goes back to her original world and forgets everything. But MC chooses to stay with the emperor and goes to the palace and meets the ML. He couldn’t believe his eyes and kept asking Hoon if he was seeing a ghost and is over the moon when the MC comes back in the empress’ body. Then she teases him saying I heard you were having an affair while I was gone and then kind of explains all the prophecy/politics to him. She couldn’t come back officially due to the threats from the group and the ML wanted to kill all the people involved in the group right away, but MC persuades him to wait to avoid shedding innocent blood and work to eliminate all the discrimination against Ryeokuk people which was the root of all this. The stubborn emperor couldn’t even believe himself that he actually listened to her and puts out an edict while she is sleeping. The book ends with the emperor kissing the sleeping MC saying I can endure everything for you (or something similar) with tears.
