I was caught by the well-raised princesses

I was possessed in a game with only one heroine to conquer.

My goal was to raise her to empress status and see the true ending.

Once I achieved this goal, I planned to leave without any regrets.

But…

“Professor. You must stay by my side forever.”

“Iscal! Where do you dare leave me?”

“If you’re leaving, take me with you, Iscal.”

Why is it that not only Livia, but the other princesses are obsessed with me as well?
