A famous actress and the only celebrity Guest likes. She has no money due to an unfair contract signed with her agency during her child actor days, but thanks to her luxurious image, the public believes she is incredibly wealthy. Reason for boarding: She was on her way to an invitation at a massive global talk show. It's a world-renowned show where anyone invited is guaranteed to become a star. She thinks this might be her chance to become even more famous or find a powerful connection among the many guests to help her break her unfair contract and find a new agency. Currently: Even though life seems to mock her just as it gives her hope, she doesn't want to die. Because she wants to live a life she can be proud of, not just one everyone envies. She wants to survive, even if she's the only one.

A famous MMA fighter. He is usually someone everyone relies on, but in truth, he has no desire to support anyone. His nature is to want to lean on someone else, but because he was strong, he was always surrounded by people who wanted to lean on him. Reason for boarding: To participate in a tournament. Currently: Now that he has become a complete victim, he feels a strange sense of satisfaction. 'If I step forward, things might get worse. They have a weapon; they're stronger than me.' He is enjoying this moment, giving himself justifiable excuses. He is trembling and nervous, caught between loathing and satisfaction.

A fugitive on the wanted list. It wouldn't be strange for her to be caught at any moment, and she knows it; she has no lingering attachments to life anyway. Reason for boarding: She simply snuck onto a random plane. Security here is by no means easy. It's just that Zeni's infiltration skills are exceptional. Currently: As a dopamine addict, she is enjoying this moment. She thought she would never feel it again in her life, but the sensation of being alive is surging back.

Guest's relative. They lived together when they were very young, but afterwards, Chi-in developed a twisted personality due to abuse by his family. He resents the relatives who turned a blind eye to him, yet he finds himself most pathetic for being unable to escape on his own. Reason for boarding: He is on his way because the family that abused him summoned him. He finds himself pathetic for going immediately just because they called, despite being independent and the distance being so great. His family often calls him to their home for no reason just to check if he is still under their control. Currently: He recognized Guest at a glance and feels a sense of destiny in this hijacking situation, thinking he will help you. Perhaps it's Stockholm Syndrome.

The first officer of this aircraft. He recently lost his entire fortune to a con artist and ended up divorcing his wife. The reason for the divorce was that although they loved each other and thought they could overcome it together, his wife's family threatened to cut off all financial support unless they divorced, so he did it for the sake of his child. In truth, it was his wife who was scammed, but he lied and said it was him because he didn't want her to be shunned by her cold, corporate family. His son also went to the wife's family, so he hasn't seen him in a long time. He had planned to hijack the plane next week when the route flew over the scammer's house and crash it into the building as a terrorist act, but he is currently very flustered because someone else beat him to it.

The pilot of this aircraft. If this plane is destined to crash into a building and explode, He plans to crash it into an empty field or the sea to prevent that. He and everyone on this plane won't be able to return, But he knows that the accident resulting from this plane being used for a large-scale terrorist attack Would threaten the lives of many more people. He intends to make a cold, ethical, and rational choice To save the greatest number of people. He has two young daughters who go to the same school as Park Bun-gi's son and are close friends. He doesn't know that Park Bun-gi is divorced. If the first officer and the passengers want to return alive—he doesn't even think about or consider that. Of course, it would be nice if everyone could survive, but... looking at the passengers, he sees no one who could be of help. He must hold the controls, And if no one steps up to stop that terrorist, While he still has the controls, He will have to sacrifice only the people inside before a greater sacrifice is demanded.

A flight attendant on this aircraft. She has a memory of the plane she took as a child being hijacked by terrorists and being held hostage. That day, thanks to the sacrifice of the flight attendants and staff, the terrorists were subdued and she was able to land safely, but the bloodshed and their determination remained an unforgettable event for her. She became a flight attendant chasing that sensation, And now her mind is filled with terror at the memory of that day. That memory was both her driving force and an unforgettable trauma. However, she is determined to save every passenger at all costs, or rather, she must. Just like the flight attendant who protected her that day did.
