Ethan Vale was the golden heir to a fortune, a boy who had everything until his own blood turned against him. Framed for the brutal murder of his parents by his uncle and brother, Ethan was cast into the depths of Metropolis Prison to rot. Beaten, starved, and forgotten, he waited for a death that wouldn't come. Then, the shadows parted. Enter Damien Blackwood. Known in the underworld and the boardroom as the "Living Yama," Damien is a billionaire whose mercy is non-existent and whose power is absolute. He walks into Ethan’s cell with a contract that defies logic: "Marry me, and I will give you the heads of those who destroyed you." Ethan isn't gay, and he doesn't trust the monster standing before him. But with a death sentence hanging over his head and a burning thirst for revenge, he signs his soul away. What starts as a cold, business transaction between a broken prisoner and a heartless tyrant soon spirals into something far more dangerous. As Ethan is transformed from a "prison rat" into the pampered, untouchable spouse of the Living Yama, the lines between hatred and obsession begin to blur. Damien promised to help Ethan destroy the Hales, but Ethan is beginning to realize that the most dangerous place in the world isn't a prison cell it’s in the arms of the man who owns him.

It was in the Era of Harmony, trillions of years ago, when Chaos first arrived. To stop all existence from growing rampantly and exhausting all sustenance, the Creator of the universe took on Chaos as its body, the void as its vigor, and black holes as its jaw—a combination to create a world-ending coffin, devouring the seas and setting lands aflame, reducing all to ashes! Later, millions of years ago, the gods waged wars against each other when the same coffin appeared out of nowhere, massacring their ranks and decimating the divine realm. Since then, it had gone missing, but its name continued to echo throughout the universe, leaving both gods and demons in fear! Millions of years later, a youth was buried alive and fused with the coffin where he was kept, and he became an undertaker whose name was heard throughout all worlds. "I'm really bad at saving lives, but I'm quite good with ending them," he said quietly with a cool visage. "I possess the Coffin of the Gods, and I can send anything and anyone to their deaths: humans, worlds… or even the gods themselves!"

The Ivanovas and the Vitales are well-known aristocratic families who have maintained everlasting friendship through generations. My name is Anastasia Ivanova. I have been the daughter of the Ivanovas for twenty years, only to discover just now that I was switched at birth. When I was swept out of the Ivanova’s mansion like rubbish, Lorenzo, the youngest son of the Vitale family, firmly picked me up in spite of all objections. Lorenzo always acted cold and distant toward me. I didn’t know why he came to take me into his car at that time. He whispered in my ear again and again, ‌"I’ve wanted you for a long time."‌ He pinned me against the leather seat, making me cry until my voice was hoarse. At that moment, I finally understood his coldness over the years was not indifference but restraint. Soon after, Lorenzo overrode all objections to marry me. His parents were vehemently against me, but Lorenzo directly stripped them of power and became the youngest godfather. Scarlett Montgomery tried to stop us from getting married, but Lorenzo canceled all her credit cards and threatened to send her away. I thought we would have a happy life. Three days before our wedding ceremony, he planned to send me abroad, claiming enemies might retaliate. But, I accidentally overheard him talking to Scarlett in the hallway at night. "Thank goodness. You tricked her into leaving until after I give birth. You’re so good to me!"‌ He kissed her cheek, ‌"I don’t want Anastasia know our affair. You must keep it secret."‌ Their dialogue made me devastated. But I didn’t confront him immediately. Instead, I quietly completed my immigration paperwork as a way to make a clean break with him.
