Tomorrow

a deity and head of the Celestial Chancellery, which oversees the work of various departments and makes key decisions.

The Jade Empress (Kim Haesuk)
The Jade Empress is the supreme deity and head of the Celestial Chancellery, which governs the various departments of the afterlife. She does not interfere in every operation, but makes strategic decisions and ensures the balance between the worlds is not disturbed. Her image combines majesty and detachment with an unexpected sensitivity: she sees the big picture, yet is not indifferent to individual destinies.

She stands above the team's internal conflicts and is often the one who asks the fundamental ethical question: "What's more important—saving one person or preserving the system?" Her presence reminds us that everything has a price, and any interference in a person's fate has consequences. At the same time, she is the one who gives the "Tomorrow" squad the right to exist and act, because she believes that sometimes you have to risk order for someone to have a "tomorrow."

Assistant group manager, helps organize work and supports the team. Ryonggu (Yoon Ji-on)
Lim Ryong-gu is the group's assistant manager and the team's glue. He doesn't seek the spotlight, but he's the one who holds everything together: he organizes processes, smooths out rough edges, remembers details, and notices when a colleague is burning out. He has a calm, balanced personality and knows how to communicate with people without making them feel judged.

Ryong-gu often takes on the "quiet" work: checking data, reminding about deadlines, supporting a newcomer when the leader is too busy. At the same time, he has his own internal conflicts and difficult memories that gradually unfold and explain why he chose this job in the first place—he knows what it's like to have no one there to listen. Within the team, he becomes something of an older friend for Joon-woong: he doesn't pressure him, but gently guides him and helps him adjust to the new reality.

The protagonist. A graduate of a prestigious university who can't find a job and is going through a serious crisis. After attempting to save a man on a bridge, he falls into a coma and eventually joins the special forces unit "Zavtra" to prevent suicides.
Joon-woong's character is a combination of sincerity, vulnerability, and growing inner strength. At the beginning of the drama, he seems lost: his high start (a prestigious university, a wealthy family) only heightens his sense of failure due to his inability to find a job. He has a heightened sense of justice and empathy: he can't ignore the misfortune of others—which is why he ends up on a bridge trying to save a stranger.

The leader of the crisis management team, a grim reaper with a complicated history; she handles things harshly, but genuinely wants to save people. A person of tough decisions and hidden pain. Her character is built on contrasts: on the outside, she's cold, abrupt, and intolerant of mistakes, while on the inside, she's deeply concerned and extremely responsible. She doesn't allow herself to relax, because she knows the value of procrastination: in her line of work, there may never be a "tomorrow."
