"It's nice to use the messenger, but you'll get hurt if you try to find out too much about me so be careful!"

— 707, Official profile
707 (Real name Saeyoung Choi, Baptismal name Luciel Choi) often referred as Seven, is one of the Deep Story characters available in Mystic Messenger. He is a hacker who can quickly find information on anything he can get his hands on.
Personality
For the most part, Seven displays a happy-go-lucky, outgoing, and very bizarre personality. He frequently plays pranks on Yoosung via chat room, makes fun of the other members (and himself), and, in response to just about anything, will respond with a series of "lol"s. He's essentially your typical jokester who loves cars (he owns multiple) and holds a passion for hacking.
However, the player's first impression of Seven is not the "real" Seven. Outside the chat room, and behind the humorous front he puts up, Seven is actually quite depressed and serious, and he refuses to believe that anything good can happen to him. This is due to his past and his profession, as he thinks that he will endanger anyone he gets close to. This fear is brought up very often during the events of his route, usually when he is trying to push the player away.
Though he rejects the player at first, it is evident that he values them quite a lot and very readily displays affection when convinced that the player will accept him regardless of how he is. After his route, he returns to his previous self, just toned down a little bit.
It is also mentioned that he is Catholic and later in his route he shows his religious values.
Appearance
Seven has scruffy vermillion hair and golden eyes. He usually wears his black jacket with amber accents. He is 175 cm (5' 9") tall, and weighs 69 kg (152.1 pounds). He is always seen wearing his glasses, which are yellow with dark grey (some times depicted as black) stripes. His orange headphones are seen around his neck the majority of the time. He also wears a silver cross necklace.
Seven changes his outfits very rarely. His attire for the party consists of a white vest decorated with red accents over a black dress shirt and a red tie.
He does cross dress and cosplay often as the player will be able to obtain pictures of himself in various costumes over the course of game play.
Background Story
Seven grew up with his younger brother, Saeran, until he was 14 years old (15 by Korean Age), in a toxic household. His father is the current prime minister and a candidate in the current presidential election; their father knew he wouldn't do well in the election if the information that Seven and Saeran were born out of wedlock (by a woman who isn't his wife) was leaked, so their mother decided to hide Seven and his brother in exchange for money. Their mother abused Saeran because he was weaker than Seven and got sick more often. Saeran's punishments included being tied by the legs to the kitchen so he couldn't leave, being beaten, and being starved and dehydrated for days.
Seven took it upon himself to change their future. Seven studied how to hack using a book he found on computing, promising Saeran that they would run away together. He met Rika at a church, and later on, V. When Seven was 14, V told Seven to take on a new name and work at a intellectual hacking company, but that he was not allowed to take Saeran with him. Seven refused at first, but after a lot of convincing from V, he left Saeran behind, entrusting Saeran's safety to V and Rika.
Deep Story
Seven engages in friendly conversation with the player, and everyone can tell he is fond of her. He becomes distracted at work because of his growing feelings, and builds a fire-spewing dog robot for the player. However, Vanderwood, who turns out to be Seven's superior at work rather than a maid, continues to visit him at home, pressuring him to finish a job from an important client. He is exasperated by coming only to help him clean and reminds him that failure to finish his work in time could mean death for both of them due to the nature of their job. Similarly, to force Yoosung into studying instead of playing LOLOL, Jumin calls his mother without permission to have her make a visit to his home.
On the 5th Day, after the messenger has been hacked, all the members of RFA start receiving suspicious emails. Unknown secretly tampers with the algorithm of the security system at Rika's apartment, and manages to unlock it on the night of the 6th Day. While working, Seven notices the changes that Unknown has made, and becomes torn with completing his work and protecting the player at the same time. Vanderwood reminds him that the type of job they do does not allow for long-term relationships and suggests on his assigned work now. Frantic, Seven steals all of his work equipment and takes them to his car, resolving to protect the player himself by personally going to Rika's apartment. He leaves the dog robot to handle Vanderwood in order to escape from him.
On the night of the 7th Day, Unknown breaks into Rika's apartment through the window, but Seven arrives on time. Seven is shocked to see Unknown is his estranged twin brother, Saeran, who he thought to have been in the care of Rika and V. The special security system then restarts, which Seven immediately warns his brother to flee before the whole place explodes, since the system is sensing Unknown as a stranger. Unknown swears to payback and manage to escape. Seven then calls for the window to be repaired. After resuming control of the security system, Seven confesses on the messenger that Rika had personally asked him to install a bomb in the apartment to destroy sensitive documents stored there. He continues to stay with the player to protect her, but is so overwhelmed by what has happened that he rejects her completely. Seven insists that the playful personality he had exuded in previous chats had all been a ruse because he is not allowed to form relationships with others since his job would endanger people close to him. When the player finds a floppy disk in one of Seven's books, he gets angry with her and tells her not to touch it.
Seven refuses to talk about Saeran and asks the player keep it a secret, and no matter how kind the player acts towards him, he pushes her away. On the night of the 8th Day, V finally returns Jumin's call, but has poor service and cannot say much because his phone is bugged. He goes on the messenger to talk to Seven, but when confronted about Saeran, he dodges the situation. Curious, V asks about whether Seven has looked at some of the documents in the apartment, and orders him not to view them when Seven answers negatively. The conversation is quickly cut off, and Seven has completely lost trust in V. The other members of RFA are also disappointed by V's actions as well, and are concerned about carrying out the party. At one point, Seven decides to quit RFA, especially since his job puts his friends at risk, which makes Yoosung angry.
Seven destroys the robot he made in a fit of anger. As he ponders about Saeran and V, he slowly starts opening up to the player. The day after, he starts fixing the robot and eventually becomes comfortable with talking about his past, where he escaped his home life with the help of V in order to ensure he and Saeran would soon live a better life. Seven even decides to show the player the contents of the floppy disk, which contained pictures of Saeran that Rika secretly took to keep him updated on his well-being. Soon enough, from reconciling with the past, Seven starts returning to his cheerful self and makes amends with Yoosung.
Against V's orders, Seven musters up the courage to open the drawer filled with secret documents. He finds an early version of the logo found in the e-mails the members of RFA received as well as blueprints for the building from where the e-mails were sourced. He is shocked to discover Rika may have been involved in the organization targeting RFA, and also may have answers to the changes in Saeran. Seven makes the decision to infiltrate the building, and the player decides to come with him.
Seven and the player enter Mint Eye and hack its computers, only to get caught by Saeran. While Seven tries to convince Saeran with the truth, that V suggested that he enter a job to erase his identity while he and Rika look after Saeran, the latter refuses to believe him, crediting his survival from his abusive home life to his "Savior." When Seven and the player show the contents of the floppy disc to Saeran, Saeran insists that Seven had put the pictures on the disc himself. He has a break down and runs out of the room, leaving the player and Seven trapped in the computer room. Outside, Vanderwood, who has come to fetch Seven, kidnaps him at gunpoint right before V's eyes.
Seven and the player escape Mint Eye, only to run into V outside. Though Seven no longer trusts V and confronts him about his blindness, V admits he saw Vanderwood take Saeran away by force. In a chat room, he apologizes to RFA and resigns as leader, appointing Jumin in his place. On the 11th Day, Seven and the player choose to look for Saeran instead of going to the party.
Relationships
Jumin
Seven's friendship with Jumin consists of Jumin rejecting his attempts to meet Elizabeth 3rd, or "Elly" as Seven nicknamed her, since his love is comparable to harassment or "abuse." Their interactions mostly relate to Elizabeth 3rd, but when Seven is in trouble, Jumin would use his authority to help him without any hesitation. Jumin also seems to respect Seven's hacking skills, and skills in general.
Zen
707 is one of the people who had helped Zen's career by spreading one certain video of Zen and earning him popularity by hacking, and making it become a virus in its own way. In Jumin's route, they seem to get along very well by continuing each other's sentences and mocking Jumin's personality change together.
Yoosung
Yoosung and Seven seem to be good friends. They were friends in high school but Seven was unable to attend Yoosung's graduation due to being abroad at the time. Seven enjoys playing pranks on Yoosung, and Yoosung is gullible enough to fall for them each time. In one of Yoosung's Bad Relationship Ending, Yoosung will go to Seven's place, after telling the MC that he doesn't really love her, where they will then fight over Honey Buddha chips multiple times a day.
Jaehee
Jaehee treats Seven with exasperation, as she tends to respond to his jokes coldly. However she doesn't really hate him, respects his intellect, and doesn't want it if Seven is neither with RFA or in the chat room anymore. At one point, she suggests that Seven should add a feature allowing members to delete messages, which shows that she does rely on him in some cases.
V
V is someone Seven trusted very much, like all the other members (except Yoosung) in the RFA do. Seven entrusted Saeran's safety to V and knowing how important Saeran is to Seven, it means Seven trusts V. He also was the one who introduced Seven to the secret intelligence agency he works for, and Seven treats V as a father figure. When V's secrets came to light, Seven was devastated by his "betrayal", to the point that he nearly quits the RFA.
Rika
He is the one who made the security system at Rika's apartment, and the only one who can enter her apartment. He first met Rika at church in his childhood. Rika gave him a book about computer skills, and along with V, giving him a new life as Luciel Choi and as a secret agent, and promised to take care of Saeran. She also once sent Seven a floppy disc filled with pictures of Saeran, despite being a secret agent is not supposed to "have" a family. Rika is very important to him, and he even once states that if he could sacrifice himself so that she could be alive again (when he believed she had killed herself), he would. However, this opinion of her was later changed, almost like a complete 180°, after Seven had found out Rika's dark secret.
