so most of the events literally happened because of a misunderstanding between Juvel and Regis. in the end all the misunderstandings gets cleared up though. so Regis’s story is sad. when he was very young he quickly became a powerful knight and was a knight for the emperor, so the emperor gets him drunk (even tho he’s a minor) and makes him sign the deal of the ring. the ring that the emperor has is called ‘Kirke’s Eye’ and can control Regis, the only condition is that he has to agree to the deal so the emperor got him drunk and made him agree. so after that he was being controlled by the emperor to kill his enemies. Even when his father (the duke of floyen at the time) got sick and died,and later even when her wife was giving birth to Juvel, he was forced to kill for the emperor and couldn’t be there. so there is this time that he find Panphil’s tomb, where he is sealed by shackles. and Panphil talks to him and tries to manipulate him to free him( he wan’t physically there, just his soul was there and could talk because he was sealed) Regis won’t fall for his manipulation but visits him every night because if something happened and Phanpil was freed he will attack the state.due to this, Regis wife thinks Regis is cheating on him because he is out every night and breaks down and becomes emotionally unstable, depressed. but Regis can’t tell her the truth because then she will also try to protect the state by going there. he just makes excuses but his wife doesn’t believe him. despite Regis and his wife fighting often, Regis really loves Juvel and they have this sweet and cute moments. and Juvels mother (regis’s wife) also plays with Juvel sometimes, other times she just emotionally relies on her daughter. so sometimes emperor controlled Regis and his wife would sometimes recognize that he is not acting like his self and that he is being controlled. then there was this time when Juvel was young , the emperor controls Regis and tells him to bring and destroy the most precious thing to him because the greedy wants to find Regis weakness. Regis most precious thing was Juvel so poor regis is being controlled and goes to bring Juvel and kill her. so when he gets there Juvels mother will tell Juvellian to hide inside the closet and asks regis who he is and what happened to regis(it was regis and he was just being controlled)so when he asks her in a robotic voice where is Juvel and starts looking for her, Juvel will run from the closet because she thinks her parents are fighting and goes to get help from the vassals and servants outside the room. they just coldly ignore her. and when Juvel comes back to the room her mother is dead and her father is crying in front of her dead body. she thinks her father killed her, when in truth the vassals who coldly ignored Juvel earlier were assassins and knights sent by the emperor and they were the ones who killed her mother. at Juvel’s mother funeral when she sees her father she screams and is scared of him because she think he killed her mother. Regis was very depressed and sad about this. so this continues and Juvel will seriously faint and lock herself in her rooms and similar things. so Regis wants to help her so he will make a deal with Panphil. So Regis has this pendant relic thing that got passed down in his family. it can release phanpils shackles. Regis will say that he will half release Phanphil if he seals his daughter’s memories. so after that she will lose the memories of what happened and won’t break down anymore. but Regis acts cold to her because she thinks she is scared of him and that she hates her. he think he doesn’t deserve her love. and Juvel misunderstands and think that he doesn’t love her and wants to get recognized by her father. so in Juvels first life the reason Regis doesn’t come to her coming-of-age ball is because that knight he was being controlled by the emperor, and the next day he really regrets it. so the only reason Regis was being nice to Mikhail was because he was Juvels lover and he wanted her to be happy. but Juvel misunderstands that he favors him because he is a powerful knight under him. what exactly happened when Princess Beatrice was poisoned in first life (Mikhail was behind it), the emperor tried to use this chance to destroy Regis’s weakness, his daughter. so he tells his that how can he trust him with imprisoning juvel when he is her dad. so Regis knows that there’s no way Juvellian is behind it and says that he will imprison her in the shadow room because she can be safe there. the sword that Regis gave Juvellian was actually a relic sword that can protect her. she misunderstands and thinks it’s for killing herself. Regis will beg the crown prince, his disciple to protect her and that he will help Max take the emperor down if he protect his daughter. so Max went to the shadow room in the request of his master, but Juvel thinks he is there to torture her so she will kill herself. after she killed herself Regis went crazy, and murders everyone and the empire went into chaos. When he was killing the emperor, he tries to control Regis with the ring.but it doesn’t work because Regis is not in his right state of mind and because he went crazy. so he kills everyone and everything. then he glances at the emperor’s crown. and thinks that the crown doesn’t mean anything if Juvellian is not wearing it. so apparently the relic pendant thingy that he has can grant a wish but it costs the casters life. so he wishes to see Juvellian again. and that is the reason was back again in her third life. the story behind the second life is that , Goddess Kirke chose Juvellian as her priest in Juvel’s first life, because God Kirke wanted Juvel to seal Paphil again. but juvel died Phanphil was unsealed and the empire even got destroyed by Regis. so she takes her to her second life, and lets her read the novel of it so she can have more information, and then by Kirke’s help and Regis wish, she is granted a third life with her last life’s memories.so this time, Juvellian thinks that there is no chance between her and Regis. and they keep misunderstanding each other.so regis will also have a dream of his first life. he thinks of it as a ‘nightmare’ and wants to prevent it. so in the end they will keep getting closer and she will get her memories and find out the truth and will tell her father about her first life. and they want to be with each other for the rest of their lives. and they defeat emperor and Phanphil together. at first regis was against max and juvel’s marries but in the end he agrees.
So, I’m going out on a limb here, but my guess is her father didn’t want her to die in the past life, I’m pretty sure he believed in her and loved her, but because he didn’t express it to her, she has never realized it, and I bet the prince was sent in by the father to check on her and keep her safe, possibly even take her away, but because she didn’t know and thought her father didn’t love her or trust her, she choose to kill herself. This entire thing makes me so sad, just thinking that if she had waited another minute or her father didn’t give her the dagger(my only assumption as to why he gave it was to defend herself or to escape maybe?) she would have learned her dad loves her and is trying to protect her, and was probably about to overthrow the king to set her free. So all in all it just makes me sad. Thank you for coming to my Ted talk.
