Living As The Tyrant’s Older Sister

When I opened my eyes, I was inside a fantasy novel world! The beauty I see in front of the mirror is the future tyrant’s older sister, Alicia! She’s not even a protagonist or an antagonist, but a character that doesn’t appear much and gets beheaded by her (future) tyrant little brother. My life is all about escaping that fate from the novel. In the end, I seduced the male lead’s merchant friend who also doesn’t appear much and was about to leave the country with him. How-e-ver– The face of the man who spent the night with me was extraordinary.
“I-I’m pretty sure the name I heard yesterday wasn’t that name but something else. Uhm, what was it. I-I think it’s Sir Lancelot.”
“Ah, that’s my friend.”
“…”
“Why, is there a problem?”
Excuse me, you’re asking if there’s a problem? A lot. There’s a lot. …Why is the male lead on my bed?!
