Confined Together with the Horror Game’s Male Lead

I became a maid in a horror game.
The one who'd give penalties and acted as a guide to the male protagonist who was trying to escape from a mansion.
I was just going to fulfil my duties until he finished the game.

"As soon as I get out of here, I'll lock you up like this too.”

The male protagonist is too noisy.
So I decided to help him escape quickly.

"Let's eat, Dietrich."
"It's a potion. You'll get better as soon as you take it."
"The hint for this stage is over there..."

For the next stage, I fed him substantially,
When he got injured, I gave him potions in order for him to pass on to the next stage,
And I even gave him clues.

He’ll be able to escape now, right?

However...

"I wonder. I can't seem to find the answer."

This guy is smart, so what nonsense is he spouting?

...The protagonist has no intention to leave the mansion at all.

"If you won't leave, I will."

I shouted in anger at the thought of having to keep seeing this annoying prick.

“It was possible for you to get out of here?"

His eyes looked down.

"I will tell you just in case, but I have no intention of leaving this place."
"What?"
"Also, you can't leave either.”

How on earth did this happen?
