When I opened my eyes after a fire, I became a side character in a novel. What am I to do now?

Get closer to the heroine? No.
Get closer to the male lead? No.
I’m going to live a long and simple life!

I’ve lived peacefully outside the Emperor’s castle for 3 years. I thought I would be free as long as the novel ended happily as it should.

“Who’s th-...”
“Servant.”

“I’ll listen to your every command.”
“H-Huh?”
“If I listen to whatever you say, can we live together?”

The servant who came into my easy life.
I live a happy life with him. Sometimes he’s a kind servant, and other times, a dear friend…The problem is, I can’t seem to take my eyes off him when he smiles saucily and flirtatiously with those red eyes.
...Is it because of my feelings?
