I Captured the Enemy Who Tried to Kill Me

I was caught up in a rampaging Gate and possessed the body of Duke Ariel, a terminally ill villain in a novel.
Magicians and Awakened Ones are like sworn enemies.
And I was the leader of the magicians.
I tried to run away from the Emperor, who is the male protagonist and my sworn enemy, but the system interfered.

Yes, let’s survive. Without revealing that I’m a Guide, I’ll escape this crazy original work and live well on my own!
I was trying to live without any presence, but…
“If you played with someone, you should take responsibility.”
The Emperor, who is the male protagonist of the original work and Imprint Candidate #1, became obsessed with me because I guided him like a one-night dream.
“Darling. You smell so good. Can we do it again?”
Serwin, an excessively pretty man who wasn’t even in the original work, smiles mysteriously and flirts with me as Imprint Candidate #2.
“I gave everything to the Family Head!”
The sickly beautiful magician who follows me around has risen to Candidate #3.
“I will protect you.”
The Emperor’s knight, who used to charge at me like an enemy, now declares he will protect me and becomes Candidate #4.
“I want to know more about you.”
And now even an upright and diligent Cardinal, full of intellectual curiosity, appears as the final Candidate #5. What am I supposed to do?
And in the midst of all this, a quest appears.
