### Autograph

**Bae Sejin (배세진)** is the the sub vocalist and visual of TeSTAR who is also an actor. At the beginning of the story he is referred to as "Lee Sejin", but later he changes his name to "Bae Sejin".

## Background

Bae Sejin is a former child actor. At the age of 11, he starred as a child shaman in a thriller film that was watched by ten million people. After that, he built a career as an actor, but after taking a long break due to poor circumstances such as being mistreated by his agency and father, he appeared in Idol Inc. to regain his popularity. He is however well-known as a child actor and has a long career in the entertainment industry. During his TeSTAR activities, he has also been active as an actor by making special appearances in dramas or attending acting awards as a "veteran actor".

In the group he has the position of sub-vocalist and visual as well as being in charge of public recognition by making use of his child actor career. Because of his excellent acting skills, Bae Sejin has the role of conveying the concept of TeSTAR's songs in their music videos and on stage. If there is a job to act in music videos or commercials, Bae Sejin is the most likely to take on that role. He also plays major roles in variety shows and movies.

Just before his debut, his former agency published an article about unfair contracts with his current agency, T1. He had a temporary mental breakdown, but with Park Moondae's advice, he revealed his slave contract in a handwritten letter with the nuance that he had been coerced and pressured by his former agency and conveyed to his fans how he felt about 'becoming sincere about his idol activities' and was completely freed from his former agency.
Since he was young, he has often encountered external situations that were difficult to resolve on his own, such as my parent's divorce and being taken to a vicious agency, which led to his mental health deteriorating and depression. He acted quite passively before, but from then on, he did not avoid bad situations even when they occurred. He changed my mindset to try to break through head-on.
Before Ryu Gunwoo's return, he was arrested for a drug distribution scandal that his biological father was presumed to be involved in, but in this life, he made up his mind before the incident occurred and succeeded in severing ties with his biological father and sending him to prison. Not only did he record his father's threats, but he also reported to the police an illegal gambling house where fraudulent gambling was taking place, and because drugs were found there, his father was imprisoned without being able to gamble.
Regardless of position, Bae Sejin's entertainment industry experience and connections are unrivaled within the group. Ryu Chungwoo and Seon Ahyeon were ordinary individuals, while Lee Sejin, Cha Eugene, and Kim Raebin were just trainee idols. Park Moondae when he was Ryu Gunwoo, while has a lot of experience as a data seller, is not as well-connected as Bae Sejin. However, Park Moondae is skilled at legal battles. Therefore, if there is a program he wants to appear in, he often seeks the help of Cheongryeo or Bae Sejin. Moreover, in Part 2, after the agency became independent, T1 left Stars Orbit out of the industry to secure demand for a newly launched survival program. They also used it as an outlet for venting anger due to political pressure from corruption. Even when it was difficult to find people to work with, Bae Sejin utilized his connections in the film industry to find filming staff.
Unlike other STier members who momentarily 'possess' their TeSTAR-self, Stier Lee Sejin only makes his appearance in the world of the System where he meets Park Moondae. Despite what Park Moondae expected him to be, a difficult person with a lot of trust issues, Lee Sejin A turned out to be a very calm and mature man with firm thinking. He is self-aware of his own efforts and easily acknowledges that he did not exactly lead a happy life. Despite the unfair situation but he learned to be strong because being upset doesn't solve the problem yet he managed to keep his caring nature, offering his help when needed.

In chapter 511, he tells the other STier members that he fought the drug case until the end and won. Although the charges against Lee Sejin A were not clear, public opinion caused the ruling to change and he was sentenced to first-trial imprisonment. In the second instance, he appealed against the allegations, the public opinion of him also became worse, and he was sentenced to prison in the second trial. The topic of his trial cooled down and there was no room for further controversy. However the third time, he won the case in the Supreme Court with all the evidence he gathered (from bank accounts, testimonies, and accomplices that came forward, etc.) despite people expecting a little chance the result would turn out clean. Fortunately, Lee Sejin A found a contradiction in the statement of his biological father, who fell over himself to convince the judge to lessen his sentence, and overturn the case. Despite his bad luck, it was his tenacity, persistence, and meticulousness that pushed him out of the sticky spot he was in and won after years of hard work and trials. He admits that, even if he wins the case, it doesn't mean that the already disbanded STier will return, but he still wants them to know that Stier didn't fail because they deserved to fail, but because they were falsely accused, and he wanted to prove to the other members that it wasn't their fault and change how they recall those memories.
Even until the end, TeStar Bae Sejin doesn't fully regain his memory. He only regains parts of his memory that Stier Lee Sejin A let him know about, such as Park Moondae's involvement, his charge for transporting drugs, his arrests, past trials, painful times, and vivid feelings of Lee Sejin A back then, that information that was already filtered by the other so that Bae Sejin can digest them easier. However, it's enough to make him realize that his current situation, he didn't come this far because he met and was encouraged by a team of good people by chance but he is the person who could endure the worst and continue to thrive, the realization led to him gaining great mental growth.

## Appearance

Bae Sejin is a handsome man with a neat and intellectual charms to him, he is usually depicted with black hair and brown eyes. He is also the second member of the Visual position in the group. According to Park Moon-dae's comment in chapter 163, he lacks muscle mass. He is not short by normal standards but when compared to other TeStar members, he is the shortest.

## Personality

He is the eldest on the team. He is the same age as Ryu Cheongwoo, but since Ryu Cheongwoo was born in October and Bae Sejin was born in February, Bae Sejin is the oldest Hyung. He always been observant, even if not socially the most adept nor shrewd. He wants to act as Hyung in his own way, but due to his timid nature, there are many cases of misalignment , so rather than being reliable he seems like someone pretending to be reliable, though everyone in his group know that he cares for their well-beings in his own way.

On the surface, he has a sensitive and shy personality and does not seem cooperative and easily overwhealmed under pressure, but in reality, he is possibly one of the most persistent, meticulous, and tenacious person who always tries his best even when the odds are against him without collapsing and more than aware of his shortcomings. At the beginning of the novel he has been described that he strangely does not wanting to lose in the contest (ICorp) and practices therefore hard. He has many opposite tendencies to Lee Sejin, who had the same name at the beginning, which sometimes causes friction between the two.

When he makes a mistake or is startled, he freezes up and his pupils begin to shake. When he gets a direct compliment he is easily flustered and tried to act prideful and nonchalant afterward. As he gained experience during activities, he learned how to learn choreography by memorizing the lyrics and dance as a whole, rather than memorizing dance routines according to the rhythm like the other members.

He can be a pessimist and tends to think too negatively on occasion. In chapter 466, when given a role from the director he used to work with, he refused at first not because he didn't want to but because he worried that he might affect the group negatively with his personal activity and he was quite realistic with his reasoning. It is hard for him to accept the firm word of encouragement that things might work out, even if Ryu Chungwoo was the one who said so. He prefers objective arguments and sound persuasion by Park Moondae for his ease of mind and accepts the acting role. He's a tender person so when he knew he couldn't promote their album while filming but his teammates still wanted him to do what he really wanted, he was deeply moved and promised to work hard to pay back their sincerity for him.
He is sincere and values honesty, but it is also a catalyst that causes his tension with Lee Sejin since he thought Lee Sejin wasn't honest with him and felt unrecognized which leads to their fight in chapter 161, which fortunately was resolved quite well. He has strong moral ethics and strives to seek justice either for himself and his mother or for his team, such as his pursuit of a legal battle to sue TeStar's agency during the group car accident with their former manager or when he strived to change his former acting agency for the better in chapter 382. His ideas can be rather idealistic at times but he is logical to consider variables and listen to other opinions first before he proceeds with the legal action.

## Traits & Likes

* When Park Moondae participated in a singing contest program as "The Groom of May" and achieved good results, he excitedly exclaimed, “You sang that, so of course you won!” When Park Moondae knows that, he remembers what Bae Sejin had previously said, "I listened to 'Winter Night' well," and said, "Bae Se-jin has a dramatic singing style." it seems to be Bae Sejin's "taste".
* According to the content in chapter 282, Roommate Reassignment, he is the "ethical fighter" type. Because he has suffered a lot since childhood and has a strong sense of justice, he is the one who reacts the strongest among the members when something unfair happens.
* His favorite food is Castella.
* His hobbies are reading and watching WeTube.
* He is good at crane games and crying within 15 seconds

## ETC

* Bae Sejin & Seon Ahyeon & Park Moondae chose royal ribbon headbands on the unit stage.
* In chapter 170, he answered that he thought basic skills were the most important to become an idol.
* In chapter 190, he answered that he had never worked part-time.
* In a WeTube video titled "Bae Sejin’s story of escaping from a hole," he was caught smiling while liking a comment praising him.
* His motto is “Nevertheless”. The explanation for Bae Sejin’s characteristic "focus" is "I want to do it". In other words, if you put the two together, it means "Nevertheless, I want to do it". This foreshadowing is brilliantly in chapter 511.
* He always uses a face wash band when washing his face.
* It is said that he does not get bitten by mosquitoes easily.

## Relationships

* Ryu Chungwoo: Bae Sejin considers Ryu Chungwoo as his close friend since they're almost the same age and they take care of each other when the other is in a hard time and more honest about their trouble with each other. They're both clumsy in terms of their friendship but their sincerity is clear even in a shared moment of silence. Bae Sejin sometimes lends Ryu Chungwoo his books while in a later chapter, Ryu Chungwoo sometimes helps Bae Sejin with his work out.

* Cha Eugene: They were noted to get along well when they were roommates. Bae Sejin sometimes brought Cha Eugene's favorite candies from his mother's acquaintance's store. Cha Eugene has also been patient and playful with Bae Sejin since they were in Idol Inc, and doesn't mind the older man's sensitive nature.

* Lee Sejin: At first, Bae Sejin finds Lee Sejin to be an unpleasant company to be around, not because Lee Sejin is a bad person but because he thinks Lee Sejin wasn't honest with him and feels unrecognized for trying his best to catch up with other members, because of his past it was hard for him to open up about his displeasures and rather not be in close range with the other man by going back to his room whenever he got the chance. It was expected that their fight would happen when it exploded in chapter 161 and Bae Sejin almost didn't want to apologize at first but after hearing Lee Sejin's reasoning and Park Moondae stepping in to make his words more comprehensive to Bae Sejin, he apologized first and resolved their misunderstanding. While they didn't get along immediately their common goal and belief in hard work helped their cooperation smoother, and they slowly became more relaxed as time went on. Bae Sejin also didn't mind Lee Sejin teasing him because he knew it wasn't out of malice.

Lee Sejin A advises that his counterpart doesn't have to remember or know all of the past to grow as it can be done in different ways rather than going through pain again.

28. ↑ At first, he often showed a cautious side for fear that his opinions would break the mood, but as he gained experience, he became a little more proactive, perhaps because he realized that "if he goes too far, the members will stop him."
