Chapter 1

"If the system is real, then go ahead and trade your healthy body with your sister."

My mom's cold laugh rang out beside me, and in that moment, I finally realized I had been reborn.

In my previous life, I'd decided to test the system and chosen the swap in my mind. The next second, all of Erica Jenkins' injuries transferred onto me. The burned half of her face, the blindness in one eye, and even the limp in her leg became mine.

Meanwhile, her face instantly returned to normal. She and Mom were ecstatic, yet neither of them cared how I felt.

When I begged to reverse the exchange, they beat me up, bound me, and locked me in the room for three days. They didn't stop until I promised I would never bring it up again.

Now, I pretended to hesitate as I watched Mom grow increasingly impatient.

"But… what if it actually works?" I asked.

A grin spread across Mom's face. "Then that'd be perfect! This is something you owe Erica in the first place. If it weren't for you, would she have ended up disfigured? Would she have had to spend all those years being mocked?"

I faltered, too scared to speak. A moment later, I muttered, "Forget it. Just pretend I never said anything."

But Mom wasn't having it. She reached out and yanked me back.

"How can you be so selfish? I'm only asking you to imagine it, and even that's too much for you? If I could, I'd give Erica my healthy body in a heartbeat, as long as she never had to suffer again—"

The instant those words left her mouth, the burn scars and injuries on Erica's face vanished and reappeared on Mom's.

Both of them froze in shock.

A beat later, Erica rushed to the mirror. Once she confirmed that her face had recovered, she pressed both hands to her cheeks, too overjoyed to speak.

Mom, on the other hand, panicked. She glared at me in disbelief. "What is this? What did you do?"

I shook my head frantically. "I don't know. The second you said it, the system suddenly notified me that the swap was successful…"

Mom was on the verge of breaking down as she clutched her scarred face. "Then switch it back this instant!"

"No!" Before I could respond, Erica hurried over. "You were the one who agreed to this willingly! How can you go back on your word?

"Doesn't the system allow three chances? If you don't want to look like this, just have Bianca exchange with you!"

A cruel glint flickered in Erica's eyes as she spoke.

Only then did Mom seem to realize something. She turned to me again, her expression haughty.

However, I spoke before she could. "The exchange system only works once every three years. Since it was already used earlier, the next exchange won't be possible for another three years."

Mom's face fell at once.

Then, I added, "But an exchange can still be reversed within three days."
