cast of six four

In the year 2399, all of humanity is drawn into a game known as Doomsday Hotel. Every player who enters is given a basic hotel. The higher the level, the larger and more powerful the hotel becomes. In his previous life, Ryan Charles sold his hotel for $30 million. Little did he know that 30 days later, the Earth would descend into a doomsday, and the hotels within the game would manifest in reality as shelters. As a result, Ryan fell into slavery and met a miserable end. Who could have imagined that when he opened his eyes again, he had returned to the very day he was pulled into the game—and this time, he was bound to the strongest system. Trash men and scheming women come to provoke him? They only end up getting slapped in the face. While other players are still trying to figure out the game's mechanics, Ryan has already built a top-tier luxury hotel, gathered four beautiful maidservants, and is comfortably lying back, waiting for Doomsday to arrive.

Serena Rivers spends three years in prison for a crime she didn't commit and uses every single day of it. She trains under four of the most formidable masters the underworld has ever produced and walks out as something entirely different from the woman who walked in. On her first day of freedom she corners the cold prison warden Xavier Stone against the water dungeon wall and kisses him without apology. He is her insurance policy and she knows it. Outside, the fake heiress has stolen her shares, her younger brother demands she kneel, and her former fiance has already moved on with a new bride. She tears up the rejection notice on the spot. Moments later, the Stone family motorcade arrives, the warden reveals himself as the family patriarch, and he shows up with a hundred billion in betrothal gifts and absolutely no intention of letting anyone touch her again. Together, they dismantle every person who had a hand in her three lost years.

Ava Montague was once the most beloved heir of the powerful Montague family. But after her father, Gabriel, vanished with no memory of who he was, Ava was betrayed by her stepmother Regina and her stepbrother Kieran. Framed as unstable and dangerous, she was locked away in a prison isolation cell and treated like a psycho. She lost her voice. She was beaten, broken, stripped of her dignity. Even her last meal became another weapon used to humiliate her. Then, after four years missing, Gabriel suddenly returned, and pulled Ava back from the brink of death. But the girl he saved was no longer the naive daughter she used to be. Haunted by what she endured, Ava sets out to reclaim her inheritance and destroy everyone who betrayed her. Yet no amount of revenge can erase the darkness the isolation cell left behind. And then a man enters her life, dangerously handsome, sharp enough to see through every mask she wears. He touches the wounds she’s spent years trying to bury. But can the part of Ava that once believed in love, the part she thought died long ago, ever come back to life?

Four years of marriage. One signature—his own—that set me free, though he never realized what he was signing. I was Sophia Moretti, the invisible wife of James Moretti, heir to the city’s most powerful mafia family. But when his childhood sweetheart, the dazzling and privileged Vicky, returned, I finally understood: I had always been temporary. So I played my final move. I slid the papers across his desk—divorce disguised as routine university forms. James signed without a second glance, his fountain pen scratching across the page as carelessly as he'd treated our vows, without noticing he was ending our marriage. But I walked away with more than my freedom. Beneath my coat, I carried his unborn heir—a secret that could destroy him when he finally realized what he'd lost. Now, the man who never noticed me is tearing the world apart trying to find me. From his penthouse to the underworld's gutters, he's turning over every stone. But I'm not some trembling prey waiting to be found. I rebuilt myself beyond his reach—where not even a Moretti can follow. This time, I won't be begging for his love. He'll be begging for mine.

Leo inherits his late brother's position as Alpha after seven years of dating me. He also inherits his brother's wife and the pack's former Luna, Jasmin. Each time he sleeps with her, he comforts me gently. "You're my only mate, Mia. Once Jasmin gets pregnant and gives birth to Blazetooth Pack's heir, I'll hold the marking ceremony with you." He tells me that's the only condition his family asked of him before allowing him to inherit the position of Alpha. Over the six months after returning to Blazetooth Pack, he sleeps with Jasmin a hundred times. He starts with only spending one night a month with her to sleeping with her every night. Jasmin was finally found pregnant on the 100th night of my staying up the whole night waiting for him. At the same time, I receive news of her and Leo holding the marking ceremony. Upon hearing this, my son asks in confusion, "Didn't they say Dad is having the marking ceremony with the Luna he loves? Why isn't he here to take us home yet?" "Because I'm not the Luna he loves." I caress his head. "That's okay, though. I'll take you back to a place that we can really call home." What Leo doesn't know is that I'm the only daughter of the Alpha King. I've never cared about being Blazetooth Pack's Luna.

Kang Do-hyun chooses an ordinary life as a taxi driver to avoid inheriting his father’s family business. One day, he happens to rescue Cha Eun-seol, who is fleeing a chase and has accidentally taken the wrong medication. After a one-night encounter, they part ways and return to their separate lives. Four years later, a stylish CEO shows up with a child and proposes marriage to Do-hyun.

At the banquet, despite pressure from her former fiancé Gu Jung-tae, Do-hyun’s father protects his granddaughter Kang Rumi and makes his presence known, yet he can only approach her as a “grandfather” without revealing his true identity.

However, after failing to secure investment, Eun-seol risks both her company and her board position by making a dangerous bet with her father, Cha Myung-hwan. At this critical moment, Do-hyun seeks out his father, accepts the responsibility of becoming the heir, and begins to take action himself. In the end, at a press conference, the capital and influence Do-hyun has prepared turn the situation around. Eun-seol not only saves her company but also secures full ownership, achieving both love and success.

My younger sister and I spent ten years fighting over Rowan Vale, the Alpha of Silver Ridge Pack. In my first life, I became his mate. Everyone said he was obsessed with me. Why else would he keep me carrying litters for seven years and give Silver Ridge six heirs? When I went into labor with the seventh, I nearly bled out. Rowan sent the healers away and forced wolfsbane down my throat himself. Only then did he tell me the truth. If it were not for the fact that only a daughter of the Hart bloodline could bear pureblood Alpha heirs, he said, he never would have claimed me at all. I had been useful for one thing only: giving him heirs. Now that he had enough, I had none. I died hating him. In my second life, I handed the bond papers from Silver Ridge Pack to my sister. “Go,” I told her. “You’re the one he wants.” Five years later, she was sent back to me half-starved, shaking, and marked by restraints. Through sobs, she told me Rowan had never loved her either. He had kept her because she was still a Hart daughter, because she could give him heirs, and because her scent could calm him during rut. She died less than two months later. When I opened my eyes again, I was in my third life. The unsigned bond papers from Silver Ridge Pack lay on the table between us, and my sister and I could only stare at each other. Who, exactly, did that Alpha want?

Serena, heiress to the Klein family, married Nathaniel after six years together—unaware their perfect love was his revenge scheme. Years ago, Serena's father Victor stole Nathaniel's father's drug formula, killed him, and built his empire. Nathaniel faked deep affection to get close, plotting his revenge. Serena's world collapsed: her father imprisoned, her mother dead from the shock. On her mother's funeral day, Nathaniel attended an awards ceremony with actress Vanessa. He seized Klein Biotech, served Serena divorce papers, confessed all his lies, and left her with nothing—destroying her faith in love. With friend Sophie's support, Serena rebuilt her life. She worked from the bottom at Sophie's studio while connecting with her mother's lawyer, Alex, determined to uncover the truth and clear her father's name. She faced Vanessa's humiliation but struck back calmly, partnered with veteran journalist Lee, used media pressure against Nathaniel, and hunted for evidence proving her father's frame-up. Nathaniel planned his engagement to Vanessa, but Serena exposed her secrets—turning the celebration into a farce. Desperate, Nathaniel used his power to crush everyone around her. But with help from an old servant, Serena found her mother's clues and located key witness Old John, learning the truth: while Victor had his faults, Nathaniel's father had also stolen Klein's core technology—and Nathaniel's conviction evidence was forged. Armed with proof, Serena launched her final counterattack. Together with Alex, Lee, and Victor's former allies, she exposed Nathaniel's fabricated evidence and illegal financial dealings. Nathaniel landed in prison, Victor's sentence was dramatically reduced. Serena reclaimed Klein Group, became CEO, reformed the company, helped Sophie rebuild her studio, rose from the ashes, and stepped into her own future—free at last.
