After Waking Up in a Coffin, I Started Playing Dumb

Pei Yu, who had slept for a thousand years, was woken up in the strangest way possible: inside a coffin.

He can’t remember what he did a thousand years ago, but to clean up the mess his past self left behind, Pei Yu takes his hapless older brother along and sets out to put things right.

This is entirely fictional. Please don’t flame me if it’s not your thing.

In short: My brother started out as my boyfriend, then became my husband.
