The city was soaked in the dim yellow light of the late night. Kim, 28 years old, a self-made interior designer, stood in her familiar room, her heart sinking. She knew the money was gone the moment she inserted the key into the brand-new small lock on the old wooden drawer under her desk. The fresh metallic scratch was sharp and cold, like a knife slicing through her last shred of trust.

She yanked the drawer open. Files, ledgers, and a tin box of change were still there, all except for the thick envelope she had withdrawn yesterday. Five million Vietnamese Dong, the fund for new materials for a client, had vanished into thin air. This was not the first time, but it was the largest sum yet. Kim’s heart turned to ice.

This house, where she was born and raised, now felt like an invisible cage. Inside were only three others: Mr. Sơn, her father, a man strict his whole life, valuing pride over everything; Mrs. Hoa, her mother, kind but spineless; and Bảo, her three-years-younger brother, sprawled on the living room sofa, texting and laughing loudly. He was wearing brand-new designer clothes.

Kim stood still. All suspicion fell on Bảo, the 25-year-old brother who never worked but spent money like water. The truth was glaring. Taking a deep breath, suppressing the tremor in her chest, she walked out of the room.

“Bảo,” Kim’s voice was dry.

He looked up, annoyed at the interruption.

“Where is the five million from my drawer?” Kim spoke each word distinctly, even as her heart pounded like a war drum.

Bảo’s laughter stopped abruptly. He jumped up, his eyes blazing: “What are you talking about? If you lost money, go find it. Why are you asking me? Are you suspecting me?”

Mr. Sơn’s eyes snapped open, and Mrs. Hoa rushed from the kitchen.

“I lost 5 million, Mom. The money was in my desk drawer, and the lock was forced open and the money stolen.” Kim stared directly at Bảo: “Besides Mom and Dad, you’re the only one who frequently enters my room.”

“You’re slandering me!” Bảo pointed his finger at his sister, yelling: “As if I would want your petty cash! You think you’re great just because you make money? You look down on me, don’t you?”

Kim gave a faint smile: “Five million is petty cash? Oh, I forgot, you don’t work a single day, do you?”

The comment was like pouring oil on fire. Bảo lunged, trying to slap her. Her mother quickly rushed between them, clutching him.

“Let him go!” Mr. Sơn roared: “Kim, what are you saying? You’re accusing your brother of stealing? Do you have proof?”

“I don’t have proof, that’s why I’m asking,” Kim hissed, tears beginning to well up: “But who is the one who asks me for money the most in this house? Who spends money like water without earning any? Who just bought a pile of clothes these past few days?” She pointed at the pile of designer bags in the corner of the sofa.

Bảo flinched but still argued fiercely: “I borrowed money from my friends! You don’t spit blood on people!”

“Which friend? Hân? She’s probably waiting for you to provide for her. Or is it your gambling friends?” Kim sneered.

The air in the house was taut. Mr. Sơn slammed the table and stood up, his face crimson with rage. Just as her father was about to explode, a trembling, almost inaudible voice spoke up:

“Stop it, children, stop arguing… The money… the money, I took it.”

The whole room fell silent. Mr. Sơn was stunned. Bảo sighed clearly, a smug, half-contemptuous smile forming on his lips. As for Kim, her ears were ringing. Her mother, Mrs. Hoa, had just admitted that she had forced open Kim’s drawer to take the 5 million.

“Mom… what did you say?” Kim stammered.

Mrs. Hoa didn’t dare look at her. She kept her head down: “I… I was desperate. I went to the market, people demanded their money… I made a mistake. I intended to pay you back when your father’s pension arrived in a few days.”

The lie was so clumsy even a child would see through it. Her mother had never been in debt. She was lying, lying to protect her golden boy. The pain in Kim’s chest was more horrific than the loss of money. It was betrayal.

“If you needed money, why didn’t you just tell me?” Kim’s voice was frigid: “Have I ever refused you? Or did you think I wouldn’t give it to you, so you had to force open the lock to my room?”

Her mother flinched.

“Enough is enough!” Mr. Sơn roared, not wanting to hear another word: “Your mother took it, so be it. You’re siblings, why are you making such a scene? It’s 5 million, not 50 million, why are you acting like the world is ending!”

“5 million is also money earned with my sweat and tears!” Kim screamed, the injustice rising to her throat: “I work hard, staying up all night designing, going to dusty construction sites, not for others to just take it so easily!”

“What are you implying? Are you saying your mother is ‘others’?” Mr. Sơn pointed at his daughter.

“If Mom truly needed money, she could have asked, I would have given it. But she lied to me, she covered up for him!” Kim pointed straight at Bảo: “What do you consider me in this house? An ATM machine?”

“Kim, shut up right now!” Her father yelled.

Kim knew her mother was afraid of the truth. Fine, if they wanted to protect him, she would show them the consequences. Kim pulled out her phone, deliberately speaking loudly: “Alright, if Mom said she took it, I won’t pursue it. But the lock was forced open, I suspect an outside thief. I’ll call the police to file a report and examine the scene. After all, losing 5 million is a theft case.”

“No!” Mrs. Hoa screamed hysterically, lunging to grab Kim’s arm: “No, Kim, don’t call the police! I beg you, don’t!” Her face was white.

“Or are you afraid the police will find the real thief?”

“Are you cornering my mother!” Bảo jumped up.

“Justice for what!” Mr. Sơn stepped forward, full of menace: “Do you want everyone in the neighborhood to know your mother stole your money? You want me and your mother to never lift our heads again, is that it?” He didn’t care about the truth, only his family’s pride.

“I said your mother took it! When a family member takes it, it’s not considered stolen! If you keep making a scene, I’ll…” Mr. Sơn raised his hand but lowered it, then uttered something even crueler: “Do you know Bảo has a big event coming up? You’re the older sister, don’t you know how to yield to your brother?”

“What big event of his is worth yielding for?” Kim challenged: “Is the big event going to the bar, gambling, or buying a new car to take Hân out?”

The words struck a nerve. Bảo’s face turned pale, and her father was seething.

“You… you speak disrespectfully! He’s your brother! No matter what, he’s your brother! You’re the sister, you have a responsibility to him!” He hissed.

“Responsibility?” Kim laughed maniacally: “I’ve had responsibility for ten years, Dad! He’s 25 now! He’s not a child anymore! He’s an idler!”

“Shut up!” Smack!

Kim’s left cheek burned. The world seemed to stop. Mr. Sơn, the father she revered and feared, had slapped her. Not for disrespect, but because she had spoken the truth. The metallic taste of blood immediately trickled from the corner of her mouth.

The most humiliating thing was that outside the door, Hân, Bảo’s girlfriend, had been standing there, leaning against the door frame, arms crossed, watching her with a look of pity mixed with mockery.

“You hit me because I spoke the truth, didn’t you? Because I hit a nerve and exposed your failure as a father, so you took it out on me?” Kim stared at him, her voice trembling but full of rage.

“You ungrateful child! I’ll beat you until you realize!” He raised his hand again, but her mother lunged to grab his feet.

“You want to leave, don’t you?” Mr. Sơn’s voice was icy: “Fine, you go. But before you do, leave 200 million here!”

Kim spun around: “200 million? For what?”

“For the money I spent raising you and educating you all these years!” Mr. Sơn stated clearly: “Give me 200 million to clear your debt to me, then you can go wherever you want.”

He was demanding payment for her upbringing. But his final words truly killed all remaining affection: “I’m telling you, I need that 200 million to pay the last installment for Bảo’s new house. He’s the son, he’s getting married soon, he must have a proper home, not squatting here like you!”

So that was it. They had planned to use her money, her sweat and tears, to buy a house for Bảo, and when she was no longer useful, they would kick her out, but not before squeezing out the last drop. The slap no longer hurt. Kim’s heart was utterly numb. She silently turned, walked back to her room, and slammed the door shut, locking it. That night, her family truly died to her.

Kim left the house, taking only a small suitcase, her savings book, and the old notebook hiding the secret for 8 years. She took refuge at her best friend, Linh‘s place.

During those sleepless nights, she recalled everything: her father tearing up her university acceptance letter, forcing her to study at a vocational school to save money, working to support her brother, and the unfairness that had soaked into the very fabric of this family.

Then, she remembered the secret. At 20, after her dream was shattered, she went for a DNA test. The first result confirmed she was the biological daughter of Mr. Sơn and Mrs. Hoa. But the second test, which she secretly conducted using Bảo’s hair, confirmed: Hồ Văn Bảo is not biologically related to Mr. Hồ Văn Sơn.

Bảo was not her father’s son.

She had hidden this truth for 8 years, fearing the family’s collapse and her father’s humiliation. But now, they had beaten her, disowned her, and used her as a sacrifice. “If they don’t consider me a daughter, I don’t need to consider them family anymore.”

The DNA test result—a tragedy 8 years ago, was now Kim’s weapon.

After Kim successfully tricked Bảo and Hân into a situation where her parents had to pay 20 million to avoid a police case for Bảo, her father called, desperately demanding she return to the police station and claim the stolen bank card (which Kim had planted, belonging to her friend Nam) was hers, to save his golden boy. Kim knew it was time to end it.

At the police station, amid her mother’s pleading, Bảo’s empty promises, and her father’s roaring commands, Kim stood firm.

“My name is Hồ Thị Kim,” she stated, her voice clear and distinct. “I am the biological older sister of Hồ Văn Bảo.”

She turned to her father: “Mr. Sơn, you are a little late in saying that. You disowned me the night you beat me and drove me out. But as you disown me, don’t you see the pathetic irony? You are abandoning your only biological daughter to protect… whom?”

Then she held up the second test result: “Hồ Văn Bảo is biologically related to Mrs. Nguyễn Thị Hoa… But Hồ Văn Bảo is not biologically related to Mr. Hồ Văn Sơn.”

Absolute silence descended upon the room. Her mother fainted. The police officer was wide-eyed. And Mr. Sơn, his entire world collapsing, stumbled back. He looked at his wife, the betrayer. He looked at Bảo, his golden boy, the child of another man. Then he looked at Kim, the daughter he had beaten and driven away. He grabbed his chest, his face turning purple, and convulsed, falling to the floor.

“Dad!” Kim screamed. Her last, involuntary reflex.

Amid the chaos, Kim saw Bảo. His eyes were cold, dark, and filled with hatred. The hatred of a cornered beast who realized he had lost everything.

Kim did not go to the hospital. She had delivered the ultimate truth.

After Mr. Sơn’s stroke, Bảo immediately seized all his parents’ pensions, brought in his delinquent friends to drink, gamble, and vandalize the house. Mr. Sơn was paralyzed and mute, forced to lie in his own filth, witnessing his “golden boy” tormenting his wife and destroying their home. He remembered Kim, the daughter he had wronged, and cried silently.

Mrs. Hoa was forced to care for her paralyzed husband and serve Bảo. When the money ran out, Bảo, now a fully-fledged monster, threatened his mother with a knife to force her to sell the house. Mr. Sơn, unable to sign the papers, was starved and neglected. In a final, desperate act, Mrs. Hoa fled the house and found Linh, begging her to call Kim to see her father one last time.

Six years after leaving, Kim, now a successful business owner with a loving husband and twins, flew back. She found her mother, frail and utterly broken. Hateful feelings were replaced by pity. Kim, along with the police, went back to the old house.

Bảo was arrested for elder abuse and attempted theft. He cursed Kim, but she didn’t look at him. She rushed to her father’s room. He was emaciated, his eyes sunken.

“Dad!” Kim cried, embracing his frail body.

He looked at her, his lips trembling, struggling to speak. With his last ounce of strength, he managed to utter: “I’m… sorry… my… child…”

“I forgive you, Dad. I forgive everything. Rest in peace,” Kim sobbed, her tears washing away all the bitterness.

He smiled, a crooked but peaceful smile, and closed his eyes.

Bảo was sentenced to five years in prison. After the funeral, Kim took her mother back to Saigon.

“Come live with me, Mom,” Kim said. “The hatred is gone.”

Kim had not needed the DNA test to win. The truth, time, and her will to save herself had done the job. She had lost a family, but she had built a new, genuine one.
