The Wooden Fish Keeps Knocking, and I Play the Real Mother in a Stepmother Novel

Song Ziyi transmigrated into a book tagged [Reformed Playboy] and [Stepmother Romance].

And she was the playboy's late first wife.

Her son would even fight his father to the death over the heroine, his stepmother.

Yikes.

Song Ziyi was also bound to a Rich Lady System.

System: "Invest in a major character in this book, and you'll receive life-force in return."

The major characters were her son, her husband, and the heroine, his stepmother... everyone but her.

Fuck!

Investing in men? That was bound to end badly.

Song Ziyi bought the heroine a house and gave her shares.

System: "Host, you've lost your mind! The heroine is no relation to you. You'd be better off investing in your son."

Song Ziyi: "You're right. I'll go marry the heroine, then."

System: "..."

Stepmother romance: check.

Tycoon System: check.

The plot will blend in more popular genres.

Theme: Think bigger and choose carefully.
