For Ron, a 21st-century otaku, being the male lead of a transmigration novel takes too much effort.

Is there a role that doesn’t require effort but still leads to endless sweet rewards?

Yes, brother, there is! A live-in son-in-law!

Thanks to a blood contract, the utterly talentless loser Ron—with zero magical aptitude—becomes the live-in son-in-law of the mighty and proud lady Feng Aotian!

The bad news: Feng Aotian already has someone she loves.

On their wedding night, Ron catches the two of them in bed!

The good news: Ron doesn’t care about them at all!

She can live her life however she wants, be with as many guys as she pleases—what’s it got to do with him?

Ron just needs to slack off, take it easy, and remember to eat when he’s hungry so he doesn’t starve to death.

As long as he sticks to this plan, Ron—who now owns assets worth trillions—can enjoy the life of a carefree playboy!

Visiting catgirl cafés, disciplining disobedient half-dragon maids…

Thanks to Ron’s outrageous lifestyle, his manor becomes an infamous den of debauchery!

However, what Ron doesn’t know is…

Many of the girls he randomly took in at the Red Palace are not who they seem—

One is a dragon princess who took human form after falling from grace.

Another is a scheming demon princess who ran away from home.

And one of them is even a yandere, amnesiac witch who once destroyed a kingdom!

When the truth is finally revealed—

Those once-obedient maids reappear around him with entirely different faces.

“Damn you, Ron—do you remember how you humiliated me back then?”

“Lord Ron, I remember you loved seeing me in white stockings…”

“Ron, didn’t you say you’d stay by my side forever?”
