The Real Young Master Chooses to Seduce the Fake One

Twenty years ago, the Ning family's child was deliberately switched by the nanny.

The real young master was sold into the mountains and spent twenty years living worse than a dog or a pig, while the fake young master took his place and enjoyed every luxury.

Everyone assumed the real and fake young masters were bitter enemies who couldn't stand each other. But nobody expected that, while they fought fiercely and wouldn't leave each other alone during the day, the two of them...

Were practically kissing each other's mouths raw behind closed doors!

The onlookers, eating popcorn: So? Are we part of your play too?

Probably a love-hate story about intimacy games.
