I grow stronger by making my wife happy.

Silver just wanted to grab a quick bite before heading back to work until he was shot dead.

When he wakes up, he finds himself inside an apocalyptic novel… as the villain.

A useless yet somehow talented one at that.

Worse, he has a fiancée, a woman who sees him in the worst light ever possible thanks to the villain’s past actions.

Now, to survive in a world overrun by beasts and chaos, Silver must do the impossible: win over the woman who hates him.

Fortunately or unfortunately he gains a system.

A strange one.

A system that rewards him for making his wife happy.

Sometimes, the rewards are small.

Sometimes, they change everything.

And sometimes… they affect both of them.
