In his past life, Ethan was thrown straight to the flesh-eating horde by his bitter rival, Ryan.
Reborn days before the outbreak, he liquidates every asset he owns to build an impenetrable fortress—trading useless paper wealth for heavy steel plates, industrial deadbolts, and hard inventory numbers.
Ten days later, hell opens up, and the suburbs turn into a lawless, blood-soaked meat grinder.
Then comes a frantic knock on his heavy security door.
It’s Mara—Ryan’s drop-dead gorgeous, curvaceous wife—soaked to the bone, desperate, and begging for shelter.
Behind his wall of monitors, Ethan looks down at the security feed with absolute, icy detachment.
"My fortress. My rules. Out here, I call the shots."

In my past life, I spent everything loving Ronald Wright, only to watch him chase after his first love and marry her in the end. I died alone and sick in a hospital, forgotten.

After being reborn, I gave up. On our wedding anniversary, I asked for a divorce. I walked away from being a full-time housewife and became the youngest rising star in the design world.

But something changed. The husband who once ignored me suddenly cared. He came home every day, afraid I might cheat on him.
I sneered, “One day, you’ll be the one begging for a divorce.” He laughed, “Keep dreaming.”

I waited for him to realize, just like in the past, that he still loved the other woman and would force me to leave, giving me millions in return.

But this time, he pulled me into his arms and said, “What’s money after a divorce? I’m worth billions. It’s all yours. But you—you’re mine.”

In his previous life, Evan risked his life to protect his fiancée and brothers in the apocalypse, only to be pushed off the fortress and fed to zombies. She thought she had obtained the address of the supply warehouse, but he had already been watching her affair with her lover on surveillance cameras.

Thinking she had his Noah's Ark, she was thrown into an empty warehouse on the day the virus broke out, and then sold as a bargaining chip by the mob.

When the zombie horde surged in, his former "white moonlight" and "true love" knelt before the fortress gate, begging him to open it.

Evan coldly uttered: "This time, it's your turn to taste despair."

After ten years of being a "consumable," I performed my final maintenance on the very day Vivian handed my life's work over to someone else. I didn’t argue or resist; I just signed the paperwork with a smile. When the Thorne Tower began to collapse floor by floor due to my final permission error, she finally realized that all the brilliance she boasted of was nothing more than the residual warmth I had fed her. Now, she kneels in the ruins, begging me to turn back time. I only find her voice… annoying.
