Jesse Venetiaan/Story

Story
Prior to Jung Yese's transmigration, Jesse Venetiaan was sent to the Riester Empire as a Confessional Priest, though it was no secret that his purpose for coming was to also serve as a diplomatic hostage. On his way to the Empire, his group had briefly passed through the thoroughly guarded inspection site of the Temple of Vigilance, which was later a reason for Jesse to be suspected of stealing the Paten of Wishes (though such a claim was eventually proven false by Cardinal Aurélie Boutier's Holy Domaine).

He arrived at the Riester Empire's Imperial Palace on March 17th (with Jung Yese having transmigrated upon waking up on the 18th ), where he was then sent to live in Juliette Palace. He only brought a bag with him, consisting of a few clothes and a small notebook—though, Yese (as Jesse) notes that not even a single drop of ink had been written in it.

After writing down a list of what he knows about QNW, he ultimately decides that the best way to increase his chance of survival and avoid his original fate of dying on the battlefield while shielding the Imperial Crown Prince and male lead, is to not get involved with both Cédric Riester, and the female lead of the story, Christelle de Sarnez. ""

For the first five days after his transmigration, Jesse's usual morning routine consisted of "eating breakfast, rolling around doing nothing for a while, and then reading the latest issue of the  or past issues in order to learn how things worked in the Empire." And after lunch, "(he) would go out to the balcony and look over the foundation of the Empire from history books Ganael and the attendant children recommended to (him), and then went for a walk for about an hour once (his) body felt stiff."

Although, his afternoon schedule would eventually be disturbed by Cédric Riester, who Jesse wanted to avoid at all cost since he wanted nothing to do with any of the two original MCs. Unfortunately for Jesse, Romero Palace (where Cédric resides) is situated right in front of Juliette Palace, and Cédric—who was said to only occasionally use the training grounds behind Juliette Palace—suddenly began frequently visit there during the same hours of Jesse's afternoon walks. Because of so, Jesse eventually adjusted his schedule to better avoid "his landlord's" and started taking morning walks instead.

First assassination attempt
On the evening of March 23rd, Jesse was visited at night by two of his attendants, the Bellang twins, before they reveal themselves to be assassins sent by the Prince Consort of the Holy Kingdom. Unaware that Jesse possessed a stronger amount of Divine power than them, the assassins—Synkie and Peter—were rather quickly overpowered by Jesse's Holy Domain. With the help of his Divine Oracle, Jesse was able to prevent them from committing suicide for having failed their mission, and managed to hold out right until Benjamin Girardin and Élisabeth Moutet arrived alongside the Imperial Guard to arrest them. Jesse's room ended up being destroyed by an ether explosion during his struggle against the twins, and promptly fainted due to an unstable flow of ether.

While drifting between consciousness and unconsciousness, Jesse overhears part of a conversation between Élisabeth and a man who she calls "Cédie". He hears Cédie wonder in disbelief if Jesse really planned on living quietly, before succumbing back into sleep.

Upon waking up after three days on March 26th, he was immediately greeted by Cardinal Aurélie Boutier, who filled him in on the fate that would befall his assassins, and explained a bit the manner in which Synkie and Peter were able to disguise themselves as the Bellang twins and enter Juliette Palace as his attendants. Later on, Élisabeth Moutet also explained to him how she was able to figure out they were imposters, since she had met them whilst staying at Baron Bellang's when she was younger, alongside the Imperial Prince.

The Spring Ball
It is still March 26th. Upon gaining the impression that Jesse hasn't a clue on what the Spring Ball is, Élisabeth Moutet launches into a curt explanation of what it entails. During said explanation, she brings up Christelle de Sarnez, revealing that the young lady of Sarnez had been asleep for three years after her coming-of-age ceremony (held at age 16) and had only recently woken up on the same day that Jesse had fainted after being attacked by Peter and Synkie. And although Élisabeth notes that the nobles preparing for the ball fear their respective debuts being overshadowed by Christelle's attendance, she also cues in that Jesse is yet another person they would be attentively watching, especially after he was able to survive an assassination attempt thanks to his own abilities, only one week after arriving at the palace.

Jesse tells her that he would not be attending the ball, especially since he isn't even able to to take a walk in the gardens without the Empress's permission—though Élisabeth notes that after the Imperial family received scorn because of the assassination attempt, there have been talks of the Empress possibly sending Jesse an official invitation in order to restore some of the Imperial family's prestige by publicly showing that he was healthy and well.

Jesse admits to himself that attending the Spring Ball—the very place where the original main character was making her Beau Monde debut—would be even more dangerous for him than the twins' assassination attempt. So in response to this, he admits to the Vice Captain that he would be busy on the day as the ball, since he plans on properly fulfilling his role as Confessional Priest at the palace (which was what he was sent to the Empire as, alongside being a political hostage).

First training session with Aurélie Boutier
On March 28th, after waking up near 9 AM and donning a more formal attire and contacting Romero Palace to request for a carriage, Jesse set out with Benjamin and Ganael to meet Cardinal Aurélie Boutier, who had previously told him that she would open her office hours at 11 am on Mondays, Wednesdays and Fridays for him, should he have any questions for her. Though, rather than going on his (mostly) own volition—being somewhat hesitant, since he would've liked to have another extra day of rest to empty his head and get over the mental shock after nearly losing his life in an assassination attempt—Benjamin stresses with franticity that "Rather than ‘It’d be great,’ it is that you must go. Prince Jesse, this is not an option.’"

Upon arriving at the Empress Palace, he is greeted by an attendant who personally escorts him to the Cardinal's office on the second floor of the palace. Ganael wishes him a good time before leaving Jesse to meet Aurélie, though the events that follow involve Jesse not having a rather enjoyable time, seeing as his apointment with Aurélie consisted of her launching him headfirst into "training time without training equipment." The training wasn't all suffering, however, since Aurélie proves herself to be a good teacher, teaching Jesse how to use his Holy Domain to properly protect himself; how to resist against her own Holy Domain; how to detect the existence of ether and control it with Divine Power; as well as the difference between ether and Divine Power. The sudden training session ends with Jesse collapsing on top of the symbol of the Church of the Almighty God at the center of her office, and with him questioning the need for this sort of training when she had told him to come to her for answers. She answers that's she's teaching him those things precisely because she told him she would answer his questions. ""

Original story
In "I Quit My Job and Ended Up as a Noble Young Lady in Another World," Prince Jesse Venetiaan was the second male lead who ended up dying during a war after saving the life of the male lead, Imperial Crown Prince Cédric Riester.

Unlike the two Venetiaan princesses who were born from relationships between the Queen and the Prince Consort, Prince Jesse was a bastard born from the Queen’s affair with a priest. Prince Consort Werner was the one who pushed for sending Jesse to the Empire as a political hostage, presumably because he was a bastard son born from the Queen and a commoner priest, and was loved quite fiercely by the people for being born with with purple eyes that were said to show that someone was a descendant of the Almighty God, as the father of the crown princess, Werner felt concerned over the matter and deemed it necessary to have Jesse be killed.
