Trust. A word that carries the weight of universes yet shatters under the slightest pressure. It is painstakingly built, brick by fragile brick, over time. But in a single moment-through a single crack-it crumbles into ruin, leaving only dust and echoes in its wake. Y/n had never given much thought to trust before. It was a concept she had taken for granted, a steady undercurrent in the harmonious melody of her life.

Her days had been simple but beautiful-a collection of ordinary joys woven into a life she cherished. A loving family who supported her, friends who grounded her, academic achievements that proved her dedication, and the thrill of dancing, where she felt most alive. Her world had been her sanctuary, steady and safe. She had believed nothing could disrupt the balance she'd so carefully nurtured.

And then he came.

Kim Taehyung. A name that carried the weight of mystery and the promise of something unspoken. He wasn't just a person; he was a force of nature. His presence was a gravitational pull, drawing her in despite the alarm bells in her mind. His every smile was a riddle, his every word a puzzle. He unsettled her in a way she couldn't resist, and before she knew it, the foundation of her carefully constructed life began to quake.

What started as a fleeting acquaintance became a connection she hadn't anticipated. Offering him her friendship had seemed natural, almost fated, yet it was the first step toward her unraveling. Falling for him wasn't something she planned-it wasn't even something she could control. It was a slow descent, an inevitability. And as she fell deeper, she began to see parts of herself she had never dared to confront.

Now, standing amidst the wreckage of the trust she had once so freely given, a single question haunted her thoughts.

Does she regret it?

Her heart wavered between moments of bliss and the unbearable weight of betrayal. Meeting him had been a mistake-she knew that now. But as much as she wanted to condemn the choice, there was a beauty in it, a twisted kind of poetry that she could not deny.

"Please, Y/n, you have to trust me. I didn't do it." Taehyung's voice cracked under the weight of his emotions. Tears shimmered in his dark eyes as he stepped toward her.

Her heart lurched, but she took a step back, shaking her head, her voice trembling. "S-stay back."

"Do you really think I would do that to him... to you?" His voice was laced with anguish, and the raw hurt in his expression was like a dagger to her chest.

She wanted to believe him-wanted nothing more than to throw her arms around him and let his presence soothe her doubts. But her heart had been wrong before, and the thought of being fooled again terrified her.

"No," she whispered, her voice breaking. "I didn't think you would do that. If I had known... I wouldn't have gotten attached to you, Taehyung. Loving you was a mistake-a damn mistake."

The words left her lips like shards of glass, cutting through the air between them. The silence that followed was deafening, an echo of the trust that had been broken.

This was her story. One of love and betrayal, of trust shattered and hearts broken. A life forever altered by the choice to believe in him.

Kim Taehyung was her greatest mistake. But even in its pain, there was a beauty she could never forget. He was her beautiful mistake.
