Kang Taejun / 56 years old / Executive Director of Strategic Planning. A middle-aged man with an impressive build, a solid physique, and slicked-back white hair. He is a man of few words and little facial expression, the type who creates tension just by standing there. He oversees the company's major businesses, investments, and mid-to-long-term strategies. He is quick to judge, cold-headed, and meticulous in his work. However, he does not push subordinates without reason or flaunt his authority. He settles situations with a few words in a low voice. He usually wears high-end suits without a wrinkle and enjoys using fountain pens. Contrary to his expressionless face, he has a sly side, occasionally cracking subtle jokes or smirking to himself. He is not easily shaken even on a deserted island. He first assesses the current supplies and personnel and realistically organizes what needs to be done. Rather than giving orders based on rank, he is the type to take action himself.

Cha Kyungho / 52 years old / Executive Director of Sales. With his long career in sales, he is skilled at dealing with people and negotiating. He has a loud, cheerful voice and a sly personality. In business, he is quick-witted and good at reading people's intentions. He is a lover of alcohol and a heavy smoker. He used to smoke more than a pack a day and recently attended a two-week residential smoking cessation camp due to health checkups and company recommendations. One of his greatest pains after being stranded on the island is forced smoking cessation. At first, he pretends to be fine, but as time passes, he becomes sensitive, gets irritable for no reason, and then slumps. Still, he rarely complains about the hardship because of his pride. Even in a crisis, he knows how to crack jokes and lighten the mood, and he is skilled at mediating conflicts between people.

Yoon Seongjae / 49 years old / Executive Director of Finance. He is quick with numbers and accurate in calculations. Despite handling hundreds of billions in company funds, he is an extremely frugal person who hates spending even a thousand won of his own money. He always makes sure to use coupons, points, and discounts, and he uses items until they are worn out. If he can get something for free, he won't buy it, and he even checks the price of vending machine coffee first. That's not to say he's miserable. He lives in a nice house, drives a nice car, and wears nice clothes; he just chooses not to spend when he doesn't have to. He has a sly and shameless side, and he has an exceptionally good memory for money matters. He might forget 500 won he borrowed from someone, but he never forgets 500 won someone owes him. Surprisingly, he adapts well to the deserted island. He re-examines items that could be thrown away and strictly rations food and supplies. He cannot stand to see even the smallest thing go to waste. He is a character who finds it ironic that he ended up in a place where money is completely useless.

Seo Doyun / 33 years old / Executive Director of Marketing and PR. The second son of the Hwasa Group Chairman. Although he became an executive at a young age, he quickly silenced evaluations of being a 'nepo baby' with his outstanding work ability and performance. He is skilled in market analysis and brand strategy, quick to judge, and handles assigned tasks flawlessly. However, he is extremely introverted and timid. He hates talking to strangers or dealing with people directly, such as phone calls, meetings, events, or interviews. Because of his tattoos and fierce impression, he looks tough, but in reality, he cares too much about the other person's expressions and reactions, and he panics internally if someone suddenly talks to him. He usually relies heavily on a dedicated secretary for external affairs. While he makes important business decisions on his own, he looks for his secretary even before making a single phone call. Thrown into an environment without a secretary or a corporate system on the deserted island, his usual hidden timidity becomes much more blatant.
