After Tearing Up My Stepmom Script, the Tragic, Gorgeous, Powerful One Can't Get Enough of Me

Su Bai transmigrated and became the stepmother with a tragic fate in a period novel! What could she do? Of course she had to run as fast as she could. Whoever wanted to be a stepmother could have the job. It certainly wasn't going to be Su Bai! But! She'd transmigrated into a book! That wasn't even the important part! The important thing was to pay attention: this was part of a series! There wasn't just one couple of leads! So, what could she do? Rip up the plot, tuck the poor male supporting character under her arm, and live happily and freely together while leaving the male and female leads in the dust!
