The Male Lead’s Fake Sister

“Say hello, Ravia. He’s going to be your brother.”
A silver-haired man, whom my father brought in one day and called the son of a distant relative.
He was the man who would take everything from me.
My position, my family, and even my life. I am an extra, but I am desperate to regain what was taken from me, and I was destined to die for him.
‘In fact, he’s not a distant relative or anything.’
It didn’t matter.
As long as he’s the male lead, there’s nothing he can’t do as he pleases.
All I could do was play as a sweet sister for me to survive.
“I want to get along with you, Tidwell.”
I was going to run away as soon as the male lead started suspecting me. But, something’s wrong.
“Sister. Are you going to throw me away, too?”
I thought he was just suspicious of me, but what is this obsession?
“You shouldn’t have taken me into your arms if you were going to leave like this.”
