Surviving the Apocalypse with a Pocket Dimension

[Two male leads + apocalypse + pocket dimension + raising a child + supernatural abilities]

The apocalypse arrives, and they have a pocket dimension at their disposal.

Zombies and extreme weather are no threat.

They stock up, survive, and rebuild their home.

First, they slay zombies; then, they take revenge on their enemies; after that, they even find time for a sweet romance.

Huh? Where did this adorable little one come from? If nobody wants you, I’ll take you home and raise you myself.
