I’m Trapped with The Male Lead in a Horror Game

I became a maid in a horror game.

Trapped in the mansion, I either penalize the protagonist trying to escape or act as a guide.

"I'll lock you up too if I manage to get out."

The protagonist is too loud.
So, I decided to help him escape quickly.

"Let's have some food, Dietrich."
"It's a potion. It'll help you recover quickly when applied."
"The escape's hint is right here…"

I fed him well for the next playthrough, gave him potions to use if he got injured quickly for the next playthrough, and blatantly gave him hints for the problem.

We can go out now, right?

By the way.

"Well, I'm not sure of the answer."

What's with this guy who's supposed to be smart?

…The protagonist just doesn't seem to want to leave the mansion.

"If you don't leave, I'll leave."

Feeling annoyed at the thought of having to keep seeing that despicable guy, I shouted in frustration.

"Were you even able to leave from here?"

His eyes narrowed sharply.

"I'll tell you, I have no intention of leaving here."
"What?"
"And you can't leave either."

What on earth is going on here?
