The Supporting Lady Is Ready to Build Her Career

[Sweet Romance, Power Fantasy, Strong Leads] [Reborn] [Top-Tier Star] [System]

My name is Shen Yuyan, Yuyan as in arrogant and domineering.

One unexpected incident turned my world upside down.

After I died, I discovered that I was a wicked supporting female character in a book? I refuse to accept that! Why am I not the protagonist? Do it over! Do it over!

Not long ago, I was carrying out an assassination mission assigned to me by the System. My infiltration failed and I was exposed, but instead of killing me, they called me sister-in-law.

What on earth is going on? Can someone explain? Waiting for an answer online, and it's pretty urgent.

Bonus scene:

System: "Yuyan, do you want a husband? If you do, just say the word and I'll bring one right over."

In the blink of an eye, Shen Yuyan was cornered by a mysterious tycoon beside the bed. The man was irresistibly seductive: "Be good. Stay, and become Mrs. Qin!"

Wait, the pretty boy she'd been keeping had transformed into a mysterious tycoon?
