The Reincarnated True Daughter Tried to Ruin My Finals, But I Read the Book First

The day before my final senior exams, a girl showed up at my house claiming she was my parents' biological daughter.

I knew she had deliberately chosen the day before the exams to show up, hoping the shock would make me fail.

Because she was reincarnated, and I had transmigrated into this book.

The day before my final exams, my parents' biological daughter knocked on our door.

She said we had been switched at birth in the hospital and asked for a DNA test.

My mom immediately hugged her and burst into tears. "Sweetheart, we don't need a DNA test. A mother just knows. You are definitely my daughter."

The reason was simple: this "true daughter" looked exactly like my mom did in her youth.

The true daughter seemed a little stunned.

She looked at me and said, "Maybe we should still do it. Just in case I made a mistake."

"It's not a mistake," my mom wept. "You are my daughter."

But at the true daughter's strong insistence, they still had someone come over to collect samples for a rapid DNA test.

After the technician collected their three swabs and was about to leave, the true daughter spoke up at the perfect moment.

"Harper, you should take one too."

The atmosphere instantly grew awkward.

I just smiled and said, "No need. You guys go ahead."

She was persistent. "You really should. Just in case Im the one who made a mistake, it would give everyone peace of mind."

My dad said flatly, "It's fine. Harper already did a DNA test with us."

I flashed the true daughter a sweet smile.

This reincarnated true daughter had no idea that she wasn't the only one who knew the plot. I knew it too.

Because I was a transmigrator, and I actually knew more of the story than she did.

I knew long ago that she would show up at the Sterling family's doorstep the day before the finals.

She believed her past life was miserable because the original owner of my body had stolen her rightful place. So, she wanted revenge.

She deliberately chose to drop this bomb the day before the exams to catch Harper off guard and ruin her academic future.

In the original novel, the original Harper was the state's Valedictorian. But after the true daughter's sudden appearance, Harper's mental state collapsed, and she bombed the exams.

So, before the true daughter even knocked on our door, I had already found an excuse to tell my parents that I suspected I wasn't their biological child.

At my request, we did a DNA test.

The results were obvious: I was not a Sterling.

I immediately offered to move out, but my parents refused.

After all, they had raised me for eighteen years. Even without blood ties, the love was still there.

To ease the true daughter's awkwardness, my mom proactively brought up changing her name.

And so, even before her DNA results were officially printed, Olivia Hayes became Olivia Sterling.

After returning to the living room, Olivia said, "Mr. and Mrs. Sterling, until the DNA results are officially out, I should probably go back to the Hayes family."

My adoptive mother couldn't bear to let her go. She gently started asking about the Hayes family's situation.

When Olivia arrived today, she was wearing a faded, washed-out t-shirt.

I knew my adoptive mother wasn't saying it out loud, but she already assumed Olivia had a terrible life with the Hayes family and wanted her to stay immediately.

Olivia looked hesitant. "Dad is a doctor, and Mom is a teacher. Even though they don't make much money, squeezing into our tiny house together is still really happy."

I mentally highlighted the key words in Olivia's speech: don't make much money and tiny house.

My adoptive mother's face changed instantly.

Her eyes filled with heartache. "Olivia, please don't go back. Your final exams are tomorrow. Tossing and turning with all this traveling... I'm worried it will affect your performance."

My adoptive father thought for a moment before finally speaking up. "Give me the Hayes family's contact info. I'll communicate with them."

He made the call from his study, so none of us knew exactly what he said.

But not long after, my biological parents appeared at the entrance of the Sterling mansion.

The two sets of parents stayed in the living room to talk, while Olivia and I were sent back to our rooms.

Because Olivia arrived so suddenly, my adoptive mother could only put her in the guest room for now.

Once back in my room, I quickly organized my luggage and the supplies I needed for tomorrow's exams.

There really wasn't much to pack.

Since the day I realized I had transmigrated into a book, I had been preparing for this. I knew Olivia would show up eventually, and my time at the Sterlings was limited. It was better to be packed and ready than to be kicked out.

I don't know what they discussed downstairs, but my biological parents actually agreed to let me stay at the Sterlings' house until my exams were over, after which we would do our own DNA test.

When they were leaving, I walked them out.

My biological mom took my hand, her voice incredibly gentle. "Can I call you Harper?"

I nodded. "Of course."

She smiled warmly. "Harper, right now, nothing is more important than your exams. Whether we cry or laugh about this, let's save it all for after you're done testing, okay?"

She spoke so softly, offering me endless comfort.

I knew she was terrified that this sudden upheaval would ruin my state of mind.

But how could it?

In my past life, just like the original Harper, I was also my state's Valedictorian.

Olivia, on the other hand? In the original novel, after she reincarnated, she was so obsessed with scheming against Harper that she barely touched her textbooks. She ended up failing to even get into a community college.

She still didn't realize that in the original novel, both she and Harper were nothing more than cannon fodder meant to make the female lead look good.

Exam day arrived.

Olivia and I were assigned to different testing centers.

In the original book, Olivia played the insecure victim card, manipulating Mr. and Mrs. Sterling into driving her to the exam center together.

Meanwhile, the original Harperreeling from the double blow of finding out she wasn't their real daughter and being suddenly neglected by the parents who raised herperformed disastrously on her first subject.

Taking these exams is like a domino effect; if you mess up the start, your mental state shatters, ruining everything that follows.

To top it off, later in the week, Olivia secretly tampered with Harper's food, giving her severe food poisoning and forcing her to take the rest of her exams while violently ill.

As a result, the Harper who was supposed to be Valedictorian ended up barely qualifying for a low-tier community college. Meanwhile, the original female leadwho had always been forever second placeeffortlessly claimed the Valedictorian title.

And Olivia? Even worse.

Before her reincarnation, she had been out of school for years. She had forgotten everything and lacked the discipline to study. She couldn't even get into a community college, so Mr. Sterling eventually paid an exorbitant fee to ship her off to an overseas diploma mill.

Knowing Olivia was going to pull a stunt, I spoke up first at breakfast. I proactively suggested my adoptive parents drive her to the testing center.

"I already scoped out my route yesterday. I know exactly how to get there, I can just take an Uber."

Oh, you want to play the innocent white lotus? Two can play that game.

Hearing this, my adoptive mother looked instantly heartbroken for me.

Olivia was caught completely off guard. She just sat there, mouth slightly open, desperately trying to maintain her fake, sweet smile.

It was hilarious.

My adoptive father frowned. "Harper, what nonsense are you talking about? Your mother will drive Olivia, and I will drive you."

In the original book, the Sterlings were actually always very good to Harper. Even after she moved back to the Hayes family, they frequently visited her.

I flashed a harmless smile. "Okay!"

The smile on Olivia's face slowly vanished.

After the exams finished, the official DNA results came back.

Unsurprisingly, Olivia was the Sterlings' true daughter.

The moment she saw the paperwork, Olivia shot me a provocative glare before throwing herself into Mrs. Sterling's arms, sobbing loudly.

Mr. Sterling stood to the side, silently lighting a cigarette.

I walked up to him. "Dad, can we talk?"

He instinctively put out the cigarette.

He glanced at Mrs. Sterling and Olivia, who were crying their eyes out, and nodded. "Let's go to the study."

I followed him in.

The soundproofing in the Sterling house was top-tier. The moment the study door clicked shut, the crying vanished completely.

I got straight to the point. "Dad, now that the results are out, I'm planning to move back to the Hayes house today."

He froze. "Harper, have you thought this through? Our family isn't short on money. We can easily afford to raise both of our daughters."

In the original book, when Harper moved out, he tried to make her stay just like this.

They say the bond of raising a child is stronger than blood. Eighteen years of living together isn't something a piece of paper can just sever.

I smiled gently. "Dad, from the moment I found out I wasn't your biological daughter, I already made my decision."

"If I stay, Olivia will definitely feel uncomfortable. There will inevitably be friction between us. No matter who you and Mom side with, the other will feel wronged."

In this regard, I actually sympathized with Olivia.

Having eighteen years of wealth and privilege taken from you? It's completely normal for her to be resentful.

But in this situation, both she and Harper were innocent victims of a hospital error.

Harper's biological parents never mistreated Olivia. Olivia's miserable past life was entirely her own doing. She shouldn't have pinned all that hatred on Harper.

I continued, "Besides, my biological parents only have one daughter. If I stay here, what about them?"

This was the responsibility the original Harper owed them. Since I had taken over her body, I had to fulfill that duty.

Mr. Sterling fell silent for a long time before sighing. "Harper, you've grown up. You're thinking about things much more thoroughly than before."

I replied softly, "People have to grow up eventually."

Looking guilty, he pulled a property deed out of his desk drawer.

"I was originally going to give this to you as a gift when you started college. Take it with you to the Hayes house."

I shook my head and didn't take it. "Dad, I'll just pack the clothes you bought me and my personal items. I don't need anything else."

In the original book, Olivia threw a massive fit at the Hayes house specifically because of this property.

"Listen to me." He forcefully pressed the deed into my hands. "I raised you for eighteen years. You are my daughter. Even if you go to the Hayes family, that will never change."

But in the end, I still didn't accept it.

I knew that if I took this multi-million dollar property, I wouldn't be able to righteously put Olivia in her place the next time she tried to start drama.

I understood the principle of not biting the hand that feeds you.
