No, I Only Seduced the Princess?

After collapsing from overwork, I opened my eyes and stood up, finding myself in an unfamiliar body.

As an abused and belittled extra with a limited lifespan.

I had no intention of accepting the fate of dying from cardiac arrest without a fight.

“Because if I continue like this, I’ll have a short life. As you can see, I have nothing and I’m too busy trying to survive. I plan to extend my life with my white magic. Oh, and while I’m at it, I’ll get some revenge too.”

I intercepted the power that the villain was going to take and gained immense strength.

“Lord Conrad, I presume? I’m the boss of the Eileen Merchantry.”

I created a merchantry and accumulated wealth.

“What I want is not the love of the prince. It’s the position of the crown prince’s consort.”

I obtained the position of the crown prince’s consort.

Now. He just needs to seduce the adorable female lead princess and live happily ever after!

But…

“Who dared to touch my daughter-in-law?”

“Sister Adele, you can rest. I will take care of the dirty mess.”

“My lady, what are you talking about? Have I been inadequate? I will strive to satisfy you.”

I never intended to get involved with all of you, so why do you like me?
