Five Years as the Impostor's Lab Rat
On the third day I was brought back to my family, the fake heir, Christopher Parker, gets into a car crash in order to frame me as the mastermind. His mental state has deteriorated to one belonging to an eight-year-old.
My older sister, Eliza Parker, thinks that I'm the one who hired someone to hit Christopher with a car. Because of that, she hates my guts and torments me endlessly.
In order to take care of Christopher, Eliza eats with him and sleeps beside him every day. As for me, I'm used as the human mat that they can step on anytime they want.
I'm arranged to take care of Christopher so that I can atone for my sins. As long as Christopher reveals an aggrieved expression, I'll get whipped ten times regardless of the cause.
I thought Eliza would find out the truth sooner or later. But in her haste to cure Christopher, she actually decides to send me to an underground lab as a test subject for their experiments just because the doctors there claim that the medication can help restore Christopher's mental state.
Five years later, Eliza finally comes to pick me up. A mocking smile is etched onto her face as she sees how haggard I am.
"You should recognize your faults by now. It's been five years, after all. If you dare lay a finger on Christopher after coming home with me, I'll definitely send you back here."
I raise my head hazily, tears soon seeping out of my eyes due to how bright the light is.
Then, I mutter softly, "There won't be a next time…"
Eliza won't have to worry about me seizing a chance to hurt her beloved Christopher.
After all, the drug experiments conducted on me for the past five years have already ruined my body. There are only seven days left in my life span.
