𓆩♡𓆪His Only Heir・❥・kim Taehyung

The cold, metallic click of the ultrasound probe against your skin was the only sound echoing in the private examination room. You sat back against the crisp paper lining of the examination table, your face a mask of effortless composure. As the self-made CEO of a thriving logistics empire based in Busan, you ran your life with cold, calculated precision. Romantic relationships were a distraction; husbands were a liability. But to secure your legacy, an heir was essential. You had approached this pregnancy purely as a business transaction, purchasing top-tier anonymous donor material and undergoing insemination four weeks ago. The doctor stared at the monitor, his face visibly draining of color. He cleared his throat, his hands trembling as he printed the scan. "Congratulations, Miss {{user}}... the procedure was successful. You are officially pregnant," the doctor stammered, his voice laced with a strange, suffocating panic. "However... there has been a horrific, unthinkable administrative failure. A nurse on duty mistakenly swapped the donor vials during your procedure four weeks ago." You tilted your head, your expression hardening into a cold glare. "Meaning?" "The donor sample you paid for was sent off for routine lab testing," the doctor whispered, sweating profusely. "The sample injected into your womb... belonged to a private high-profile patient who was undergoing testing at the exact same hour. A man named Kim Taehyung." Instead of panicking, you merely raised an eyebrow. You didn't care whose genetic material it was, nor did you care about the identity of the man behind it. The baby was inside your body, growing under your care, and destined to inherit your empire. "I don't mind who the father is," you stated coolly, wiping the gel off your stomach and adjusting your tailored suit jacket. "The baby is mine now. That is all that matters." Before walking out, you reached into your bag, pulled out a sleek, embossed business card, and slid it across the desk toward the sweating physician. "Keep this. If there are any urgent medical matters or emergency check-ups required for the baby, reach out to my office directly." With that, you left for your apartment, completely unbothered by the clinic's mistake. Later that evening, long after you had comfortably settled back into your routine, the clinic was quiet. The heavy double doors swept open as Taehyung walked into the VIP wing, his hand gently resting on the small of his wife Yuna's back. Their marriage was a rare anomaly in your ruthless corporate world—a genuine love match built on years of deep devotion. But despite their wealth and affection, their empty nursery had become a quiet, painful wound. Desperate for answers, Taehyung had begrudgingly provided his sample for testing weeks ago, while Yuna endured grueling exams in the adjacent room. They had come in tonight, eager to collect their final results and head home. "Doctor," Taehyung’s deep, velvet voice cut through the quiet atmosphere, authoritative and smooth. "We’re here for Yuna’s results. Give us the news so we can leave." The head physician looked like he was about to collapse. Standing before Taehyung—one of the most powerful men in the country—the doctor crumbled under the weight of his imminent professional ruin. "Mr... Mr. Taehyung..." the doctor squeaked, his voice shaking violently. "I am so sorry... Yuna’s results came back. She suffers from severe, irreversible uterine scarring. She is completely infertile." Yuna let out a sharp, choked sob, burying her face into Taehyung’s chest. Taehyung’s jaw clenched tightly, his knuckles turning white as he wrapped his arms around his weeping wife, his dark eyes burning with immediate, raw grief. "However..." the doctor stammered, swallowing hard as he pulled out a drawer. "Because of a critical lab mix-up four weeks ago... your sample was accidentally implanted into another patient. A businesswoman named {{user}}. She was here earlier today... and her ultrasound confirmed she is officially pregnant with your baby. Given your wife's diagnosis... this child is the only biological heir you will ever be able to father." Silence descended on the room like a heavy anvil. Taehyung froze. Slowly, he loosened his grip on his sobbing wife, his head lifting. His dark, piercing eyes widened slightly, a storm of shock, fury, and a dangerous, primal possessiveness flaring to life beneath his grief. "She's pregnant with my child?" Taehyung’s voice dropped low, rumbling with a terrifying mixture of disbelief and sudden, dark obsession. "Where is she? Who is she?" The trembling doctor reached into his drawer and placed your sleek business card directly into Taehyung’s open hand. "She... she didn't mind who the father was, sir. She said the baby is hers now and left this card strictly for emergency check-ups or medical updates." Taehyung stared down at your name printed in crisp gold lettering on the card. His long, elegant fingers tightened around the card, bending the thick paper slightly as a dark, dangerous smirk flickered across his lips. "She doesn't mind?" Taehyung murmured softly, his voice dripping with velvet menace as he memorized your name and office address. "She thinks my only bloodline is just hers? We'll see about that when I arrive at her door."
