He provided everything Ivy needed. Money especially in change of a marriage with her and when the apocalypse started too....he ruled it with her as well as her daughters.

Elara: Sold at birth, is a servant to Alpha Draven. Elara was claimed and bitten by Alpha Draven at a young age and had her wolf removed from her. With no wolf and no power, she is stuck under his power and control. When an announcement comes out about Alpha Prime Darius looking for his Luna, Elara sneaks an entry in for herself. While hiding the fact that she is always claimed and bitten. Expecting to never hear of it again, she is shocked when the Alpha Prime Soldiers arrive to collect her. While Alpha Draven wishes to refuse and keep her, he's powerless and has to follow the order and let her leave. When Elara arrives at the castle, she finds herself standing among other potential Lunas and quickly realises that this competition was never intended to find Alpha Prime's true mate but the best candidate to be Luna. Without a wolf, she is sure she will be gone within the first round. However, she becomes shocked when she isn't sent home, but her being there is nothing more than publicity. Things become more tangled when Alpha Prime Draven chooses a Luna, and on the same day, Elara's wolf is returned to her.

It was the tenth year of the Mechanical Civilization. My girlfriend, who always spoiled her brother to an unreasonable extent, orchestrated my death. Luckily, I was reborn seven days before the arrival of the machines. I bought a heavy-duty truck and evolved the strongest mecha. Close-combat mecha, long-range mecha, weapons, shields, funnels, modules… This time, I wanted the best of everything. My name is Victor Wild. Born to be a victor, born to be wild.

I’m the heroine in an erotic story. My specialty? Turning anything hot or cold into something steamy. On the first day I landed in a horror game, the boss told everyone to choose how they wanted to die. I smiled and said, “I’ll take shortness of breath, trembling legs, glazed eyes, and… pleasure so intense I die from it.” Boss: “???”

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.
