The Male Lead and I Are Trapped In A Horror Game

The Male Lead and I Are Trapped In A Horror Game
I gave penalties to and guided the male lead who is trapped in the mansion and is trying to escape. I was just going to roughly fulfill my duties until the male lead finished playing.
“As soon as I get out, I’ll lock you up the same way.”
He talked too much. As soon as this happened, I decided to help him escape.
“Let’s eat, Dietrich.”
“It’s a potion. You’ll heal right away if you apply it.”
“The hint to escape this is over there….”
I fed him well to prepare him for the next scene, gave him a potion to help him play efficiently when he got hurt, and even gave him hints about the problem.
Well, now we can leave the mansion, right?
However…
“ Well, I don’t know about that.”
What does he mean by that?
… Dietrich had no intention of leaving the mansion.
“Well, if you don’t go out, I will.”
I was so annoyed at the thought of having to keep looking at him that I shouted in anger.
“Didn’t you desparately wanted to get out of here?”
His eyes sank bitterly.
“I’m telling you, I have no intention of getting out of here.”
“What?”
“And you can’t leave either.”
How on earth did this happen?
