The nanny, Polly Jackson, pushes me down the stairs when I'm seven months pregnant. I suffer from major blood loss and go into premature labor.

Before I can question her about it, Zachary Campbell brushes me off with a lame excuse. "Polly didn't mean it. You and the baby are fine, so don't be so petty about this."

I get out of bed to move around. I'm at the bathroom door when I hear Zachary and Polly's conversation. "Are you sure that wretch can stay alive, Zachary? Switching it out won't be that easy if it dies."

"Don't worry about whether Daisy Jameson's baby can live, Mom. Either way, mine and Danielle's child will be the Campbell family's sole heir."

I pretend I've never heard this and raise my son for 18 years. During a banquet held in honor of a share ownership transfer, Polly suddenly shows up with my mentally impaired daughter.

She cries, "Mason is my grandson! It's high time he's returned to his rightful place after being raised by the wrong family for so long!"

I'm unfazed. I even laugh at her words. "Fine, then!"

"Mrs. Campbell, Mason is lactose intolerant. Why do you keep forgetting about this?"

The nanny, Polly Jackson, grabbed the milk bottle I had been holding while chewing me out. Ever since I started caring for Mason Campbell, whom she treated like her own grandson, she did nothing but criticize me at every turn.

She was more concerned than I was when it came to Mason. Whenever he caught a fever, it was as though the sky had fallen through. Polly would stay awake through the night taking care of him.

Armed with the excuse that she had experience raising children, she interfered with how I raised Mason. Polly took over the dressing, feeding, and taking care of Mason all around, simpering about how this would relieve the burden on my shoulders.

Polly was a single mom. After claiming that her daughter, Danielle Jackson, had lived a troubled life and experienced nothing but unkindness, Danielle followed in Polly's footsteps and moved into my house.

They called my daughter Griselda Jackson and locked her up in the staff's quarters, where the sun never shined. As she had been born prematurely, Griselda was weak. Even when she cried, her whimpers were soft and feeble.

Yet, Danielle found her annoying. Thus, she fed Griselda sleep medication and claimed that sleep was good for a child's development.

Although the Campbells paid them handsomely, Griselda was constantly deprived of food and drink.

"Since Mason can't have the milk, give it to Griselda. She's a month old now. Yet, she looks extremely weak. It's time to put more effort into caring for her. If not, others will think that the Campbells are abusing our nanny's daughter."

I glared at Polly, who had been guzzling milk. She stopped.

"That little wretch will be fine with some oatmeal. It would be a waste to feed her milk of this quality. At least I can take care of Mason after drinking the milk. Isn't that right, Sonny?"

Polly played with Mason and finished her milk as he giggled.

In the evening, I changed Mason's diapers. Just as I was about to throw it into the bin, Polly took it from me.

"It's just a little pee. It's not like he took a poo. It'll work just fine for Griselda. We'll save up diapers whenever possible."

Under my disdainful glare, she put the dirty diaper onto my daughter.

When Mason turned one, Polly got him a gold statue.

She said, "When you grow up, I hope you'll be an excellent wordsmith and a mathematical genius. You'll manage the Campbell Corporation wonderfully."

Griselda, who'd been born a day older than Mason, was still wearing his old clothes. Covered in dirt, she sat in the staff quarters playing with mud.

When I signaled at Polly, she threw a piece of cake in front of Griselda.

"You little wretch. Go thank Mrs. Campbell for her generosity! In the future, you must do everything Mason tells you, even if he orders you to die for him. Understood?"

Polly kicked Griselda, which made Griselda cry.

Griselda was just a little kid. How could she possibly comprehend what Polly was saying? Griselda could only stare at the cake while drooling out of the corner of her mouth.

Polly began nagging, "You must've been a starving beggar in a past life. Not only are you dumb, but you're also a glutton. Mason has more talent in his little finger than you'll ever have, you idiotic wretch. Why can't you read the room? Keeping a dog would be better than raising you!"

Instinctively, Griselda reached for the cake. However, Polly stamped on the cake with her foot before Griselda could touch it.

"All you do is eat all day, you disgusting glutton."

Displeasure twisted my features. "Ms. Jackson, I gave the cake to Griselda. Is that how you waste my food?"

Polly would walk all over me if I didn't stand my ground as the lady of the house.

Her eyes darted to the side. Then, she collapsed before me, trembling.

"Mrs. Campbell, I'm sorry. It was all my fault. I shouldn't have stepped on Mason's cake by accident. I'll never do it again. I'm begging you, please don't fire me!"

As I was trying to figure out when Polly became so sensitive, I heard someone roar behind me, "Daisy Jameson, you've crossed a line. Ms. Jackson has been working in the family for decades. Are you incapable of offering her even a shred of respect?"

Zachary Campbell strode forward and helped Polly up. Then, the two of them brushed past me and left.

It was as though he was Polly's son.

I'd realized that whenever I showed even the barest modicum of kindness to Griselda, Polly would do her best to school me in front of Zachary.

As the children grew up, Polly could no longer keep up due to her old age. That was when Danielle took over.

One day, Mason got back from school and told me that there would be a parent-teacher conference at school tomorrow. The teacher had instructed him to bring his parents, and that we would be invited to give a speech.

However, Zachary and I were both going on business trips and were thus unavailable.

At the same time, Griselda came home to Danielle with a similar story.

"Mom, I got first place in the examination. The teachers would like you to share some insights on stage," said Griselda timidly. She handed her exam paper to Danielle.

Griselda had gotten full marks.

Danielle didn't even spare her a glance. She mocked, "You got first place? Stop lying. How could Mason score lower than you? He's so intelligent!"

Mason hadn't done as well as Griselda. He hadn't even achieved the average mark for their year.

While Zachary and I had graduated from prestigious universities with Masters, Mason was hopeless when it came to studying. The power of genetics was not to be underestimated.

Griselda steeled herself and yelled, "I'm not lying. Mason didn't even pass his exams. I'd still have a higher total grade than him even if I skipped a paper!"

Ever since she was a child, Danielle and Polly had put her down and mocked her, opting to praise Mason instead.

Although Griselda had finally defeated Mason, Danielle still didn't treat her any better.

Griselda's rebuttal angered Danielle. The pathetic bitch who'd lived like a beggar under her for years was rebelling against her authority.

Without hesitation, she grabbed a broom and whacked Griselda with it.

Griselda ran through the mansion, throwing whatever she could reach while crying out of frustration.

Danielle chased after her while panting. It was Mason who stepped in and held her down.

"I'm not who I am if I don't beat you to death today!"

Rage was evident in Danielle's eyes as she hit Griselda, not stopping even when Griselda fainted.

Mason had to call the ambulance afterward.

Danielle didn't want to go with Griselda to the hospital, so she sent Polly instead.

"Ms. Jackson, what cardinal rule has Griselda broken to warrant such a gruesome beating? You're so cruel to your own daughter. You're not beating Sonny up while we're gone, are you?"

I scanned Danielle from head to toe. Zachary stood up for her, saying, "Daisy, Danielle isn't that kind of person. She and Polly serve us with all their hearts. Griselda was disobedient, which caused Danielle's fury to boil over and hit harder than she intended to. If you think of her like that, you're invalidating the bonds we've built with them!"

Danielle stood behind Zachary with tears streaming down her face. Her eyes seemed to say, "I've already lived such a troubled life, only to be treated so abhorrently by my boss. Just let me die."

"Zachary and I were going to send you to the parent-teacher conference tomorrow as we're too busy. Now that Griselda has been gravely injured, you probably won't have time to go either. I'll tell the teachers to cancel our speech!"

Danielle's eyes sparkled after I spoke. She said hurriedly, "I've got time. How could I be absent for such an important occasion? It's Mason's parent-teacher conference! After all, Griselda won't be able to go tomorrow. I'll be free. Don't worry, Mrs. Campbell. I'll be on my best behavior!"

Her helpless demeanor disappeared. Excitement took over.

"Daisy, where would we find a family of such excellent helpers apart from Ms. Jackson and her daughter? We've got to cherish them."

Zachary slung an arm around my shoulders as he spoke, peering lovingly into my eyes.

I nodded politely.

Danielle dressed herself in her best attire the next morning and dragged Mason out the door. However, he groaned when she touched his arm.

"Ms. Danielle, you're hurting me!"

Danielle's expression changed. She asked anxiously, "Mason, what's wrong? Let me take a look!"

She yanked his sleeves up and saw a faint bruise on his arm. As though she'd unearthed a scandalous secret, she shrieked, "Oh dear! Mrs. Campbell, how could you lay such a heavy hand on Mason?"

Danielle brought his arm to her lips and blew gently on it while comforting him.

I couldn't bear to watch her make a fuss out of nothing, so I interjected, "His wound is so insignificant you'd need a magnifying glass to see it. Stop overreacting. Just because you beat your kid up every day doesn't mean I'll do the same to mine."

The more impassive I was, the worse Danielle felt for him.

"Mrs. Campbell, you can't disregard Mason's feelings just because you spent little time with him growing up! How could Griselda's worthless life be measured against Mason's? After all, he's been treasured as the only heir to the Campbell family."

Mason couldn't stand it. Then, he queried, "It's your fault. If you hadn't beaten up Griselda yesterday, I wouldn't have fallen, would I?"

Danielle's tactical mention of Griselda triggered Mason's unhappiness.

"Mom, you should send Griselda away since she's so disobedient. Otherwise, our home will always be in a state of permanent chaos. It sours my mood!"

Mason hugged my leg as he spoke. Despite his young age, he'd already begun making statements that were downright evil.

I said nothing, but Danielle agreed with him.

"Alright, alright. Mason, it was my fault. I'll never allow Griselda to show up in front of you ever again. I'll get rid of everything you dislike. Let's head to school first!"

As I watched the two of them head off, I knew that everything was playing out as I desired.

Polly resigned, saying that she wanted to return home and retire. Peace returned to our house, as Griselda never came home after her trip to the hospital.

It looked like Polly had taken her away.

At eighteen, Mason was offered a place in a prestigious foreign university. Zachary suggested throwing him a huge party and intended to transfer a portion of shares of the Campbell Corporation to him.

As Mason signed the shares transfer contract, a woman's hoarse voice interrupted his glee.

"My darling grandson, it's my fault for only recognizing you now!"

All of Zachary's relatives and business partners were confused.

"Aren't Mrs. Campbell's parents both abroad? Even if they had returned, they probably wouldn't look so sleazy, would they?"

"Look at the drooling kid beside her. She looks about the same age as Mason."

"Has this woman gotten dementia and recognized the wrong person?"

Everyone didn't know her. However, Zachary, Mason, and I knew her well. It was Polly.

Before the guards arrived, Polly pulled out a DNA report.

"This explains it. Griselda has never gotten along with me and my daughter. She has caused nothing but trouble for us. Turns out, we're not related at all. She's not my daughter. Why would she have a great relationship with us?"

"Mrs. Campbell, you and Danielle were the only ones who'd given birth in that hospital back then. The doctors definitely mixed up the babies.

"My apologies for allowing Sonny to enjoy life with you guys for so many years. I knew nothing about this back then. Now that I'm aware of the truth, it's time to swap the kids back into their rightful places."
