My Twin Brother Actually Became a Live-In Son-in-Law?

After transmigrating, Bai Qingyi discovers that he's become the twin brother of a male lead who married into his wife's family!

His younger brother, whom he had painstakingly left behind ten years ago, has become a live-in son-in-law. On top of being despised by everyone, he's also a spineless simp who keeps taking abuse and loving every minute of it. Bai Qingyi is deeply ashamed of him.

But then he sees his brother, beaten within an inch of his life, still protecting his little niece. At last, Bai Qingyi is moved.

"Even if Bai Qingyu is a cowardly good-for-nothing, he's still my brother. How dare you people humiliate him?"

Bai Qingyi sneers. That night, he and his younger brother switch identities.

That night, to the astonishment of everyone present, he slaps his brother's wife and demands a divorce.

And so, a whole new live-in son-in-law tycoon makes his entrance!
