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.

Eliza Parker brought her brother, Christopher Parker, along when she came to pick me up.

The dim basement was brighter than it had ever been in five years.

When she saw the tears glistening on my face in the sunlight, Eliza thought I was trying to win sympathy, and her expression immediately turned to disgust.

"Don't think putting on that look will make me feel sorry for you. You deserve all of this. If you hadn't hired someone to hit Christopher back then, he wouldn't be like this now."

Whenever she recalled what had happened, Eliza still felt her blood boil. She slapped me hard across the face, and my already battered face gained yet another wound.

Humiliated, I lowered my head and swallowed the bitter blood pooling in my throat.

Seeing that I wasn't resisting, Eliza frowned and turned to the staff member nearby.

"Christopher has been in this demented, foolish state for five years. Isn't the medicine you promised me ready yet?"

As she spoke, she tenderly stroked Christopher's face.

Christopher looked at me smugly, a shrewd glint flickering in his eyes from time to time.

That familiar look instantly dragged me back into the past. Every time he wore that expression, it meant I was about to be whipped.

At the thought of the pain from those days, I flinched.

Christopher smiled with satisfaction.

Meanwhile, the researcher of the basement laboratory, Gene Harding, chuckled at Eliza's words and cast a meaningful glance over Christopher.

"I told you that as long as you handed Sutton Parker over to me for five years, Christopher would definitely recover. Here's the medicine—take it home with you. After seven days, Christopher will be back to normal."

Eliza's eyes widened in surprise and delight as she reached out to take the medicine from Dr. Harding's hand.

However, he pulled back slightly at that moment and said meaningfully, "It's just that Sutton might—"

"Might what?" Eliza had no intention of listening. She simply snatched the medicine from Dr. Harding's hand and left with Christopher in tow.

Just then, Dr. Harding called out to her.

Eliza turned back with an annoyed expression.

Dr. Harding pointed at me, sprawled on the ground, and asked mockingly, "Aren't you planning to take him back with you?"

Eliza paused for a moment, then mercilessly grabbed my arm and yanked me to my feet. But after just a few staggering steps, I stumbled and fell to the ground again.

Years of drug testing had long since deformed the bones throughout my body, and my skin and flesh were close to rotting away. Every single step was an immense torment to me.

I was in so much pain that I broke out in a cold sweat, and a whimper escaped my lips.

Seeing this, Christopher crouched down beside me with feigned innocence. A moment later, he suddenly burst into loud sobs.

"Eliza, Sutton bit me!"

Eliza's expression immediately darkened.

"Sutton, five years have passed, and you still refuse to mend your ways?"

"My teeth were pulled out a long time ago," I replied with great difficulty.

So, how could I possibly bite Christopher?
