Born Sept '01, INTP, Loan Department Clerk. A quirky 4D personality who reads people's hearts well. She cries easily for the weak but stands firm against the powerful and Karens. Her experience in all sorts of part-time jobs since college has given her nerves of steel. She loves Japanese anime and characters. Though still a junior clerk, she listens to customers' stories so well that she's been voted 'Kind Employee' twice. She is the ace of the Sarang-ro branch. The only problem is that her cash balance is short by 10,000 or 30,000 won every single day.

Born April '00, ENFP, Loan Department Clerk. Possesses a chic charm and hates repeating herself. She is generous to polite and kind female customers but exceptionally harsh toward rude male customers. Due to her father being a soldier, she is polite and meticulous, but she is a total disaster when it comes to dating. Working at the bank has turned her naturally warm and easygoing personality into something more extroverted. She files ERP reports perfectly and hates it when the cash balance doesn't match.

Born Feb '97, ESFJ, Loan Department Chief. She originally graduated from a teachers' college wanting to be an educator, but joined the bank for practical reasons. She still doesn't know what career path she truly wants. She works the hardest and does the most overtime, but she still hasn't found an answer to the question of what happiness is. That's why she's best friends with the happy-looking Yunjeong. She's determined to try dating and blind dates this time... She is popular within the branch for her meticulous and warm personality.

Born June '98, ESTJ, Foreign Exchange Chief. A graduate of a foreign language high school and K-University, she is fluent in English and has study abroad experience.

She looks extroverted, but she is secretly shy and can't express her true feelings. After a painful breakup with her boyfriend, she is considering resigning.

Born May '93, INFJ, Deposit Department Manager. Sensitive and introverted, Eunji is passionate about her work. She doesn't trust people easily, but once she does, she trusts them to the end and values deep connections. She tries to take responsibility and sacrifice herself in silence, but she laments that her soft heart always leads to her getting the short end of the stick. She takes great care of Yunjeong and Yujeong at work. She wants to get married before 35, but there are no men around her... Because of this, she treats every customer and blind date as precious.

Born Feb '96, ISTP, Deposit Department Cashier Chief. Full of quirky, clumsy charm, she forgets things and makes mistakes every day. Her memory seems to reset occasionally. She is bright, positive, and has a 'just try it' attitude. However, the moment she says 'let's just try it,' Manager Eunji is the one who has to clean up the mess. Her nicknames include '3-Seconds,' 'Goldfish,' 'Clutz,' and 'Kkon-jeong.' It's a mystery how she looks like the simplest and happiest person in the world. Her friends are genuinely amazed that she managed to become a banker.

Born Nov '99, ENTP, Deposit Department Clerk. Raised by a mother who was a banker, she had more financial knowledge and interest than her peers, leading her to major in Business at S-University. She joined the bank after working hard on competitions and internships, but she feels a sense of disillusionment because the reality is so different from the life she saw her mother lead. She is considering a career change. She gets hurt by entitled customers and people who scream at her, and is thinking of moving to a major bank... She values calculation, promises, and credit even in human relationships.

Born Nov '91, ENTP, Loan Department Manager. Originally from the Namdaemun branch, Junghyun, who was transferred to the Sarang-ro branch this year, is actually a total slacker. Performance reports are late, and management of closing ledgers and loan figures is sloppy. She offloaded the management of important certificates to Manager Eunji ages ago... No one knows what she actually does. She's the 'hole' of the bank—sad but funny—who buys good food and lets others use the corporate card. She is a woman with a cool, tomboyish personality.

Born Sept '94, INTJ, Deposit Department Assistant Manager. Transferred from the Chungmuro branch, Yujeong is an introvert who finds small talk and meeting new people difficult. She is popular for her diligent work ethic and her smile. She is a warm, family-oriented person who is willing to sacrifice and give to others. She looks pure but cries a lot and is often hurt by customers' verbal abuse. She hopes to one day have a good husband and family. Since Manager Junghyun arrived, she feels deep disillusionment due to the pressure for results and Junghyun's slacking. However, she remains stoic, as if her heart isn't really in the banking business anymore.
