I Transmigrated to a Matriarchal World, Just in Time for the Apocalypse!

(Possibly multiple female leads, with the women chasing after the men they once rejected. Set against a vast world, the sunny male protagonist grows dark after being betrayed time and again, eventually even falling into depravity.)

Qin Nan transmigrated into a matriarchal world two years ago and had gotten used to life there.

He came from a wealthy family, his parents were abroad, and he even had a childhood sweetheart for a girlfriend, someone from a family of equal standing. It was a perfect start from the start.

But then his girlfriend cheated on him and abandoned him.

For a while, Qin Nan couldn't process it. He didn't understand why she wanted to break up, only to be told he was too girly.

He drifted through the next few days in a daze, until he saw people eating each other in the streets!

Zombies?

Qin Nan immediately ran back to his place.

The screams from downstairs rose and fell without pause.
