The glow of prom lingered long after the night ended. It was the kind of evening that stuck with you—the laughter, the music, the feeling of being surrounded by friends and the one person who mattered most. Hyunjin couldn't stop smiling, even the morning after, as he lounged in the living room flipping through the photos Felix had sent in their group chat.
"Look at this one," Hyunjin said, holding his phone up to Chan, who was sitting across from him, reading. "Felix caught you mid-spin when we were dancing. You look so intense."
Chan glanced up from his book, his lips curving into a faint smile. "I wasn't trying to be intense."
"Well, you pulled it off," Hyunjin teased, scrolling to the next picture. "You know, I think half the school is jealous of us."
"I only care what you think," Chan said simply, his calm tone making Hyunjin pause.
Hyunjin blinked, then chuckled softly. "You really don't know how to turn it off, do you?"
"Turn what off?"
"That whole 'perfect boyfriend' thing," Hyunjin said, grinning. "It's honestly unfair."
Chan set his book down, his smile growing. "It's not about being perfect. It's about making you happy."
Hyunjin's heart fluttered, and he rolled his eyes dramatically to hide his blush. "Okay, okay, you win. Stop being so charming."
But the truth was, Hyunjin didn't mind one bit.
The days after prom felt quieter, more peaceful. But that peace was soon interrupted when Chan found something unexpected in Hyunjin's father's study.
It happened by accident. Dr. Hwang had asked Chan to help reorganize some files, a task Chan didn't mind doing. As he worked through the piles of papers and binders, he noticed a folder labeled "Project Son - Final Notes" tucked at the bottom of a drawer.
His hands froze. The name alone was enough to send a ripple of unease through him. Glancing around to ensure he was alone, Chan carefully opened the folder.
Inside were documents detailing his creation—schematics of his internal systems, notes on his programming, and, most surprisingly, handwritten observations from Dr. Hwang. The notes were dated years ago, long before Chan had ever come to live with the Hwangs.
"Day 183: Subject continues to exhibit behaviors beyond initial programming. Adaptive learning appears successful, but emotional response remains a concern."
"Day 276: Kang's original intent for Subject is clear—this was meant to be a continuation of Minyoung Kang's legacy. The resemblance is uncanny, but I fear it may be too much for Kang to bear. His grief is palpable."
Chan's chest tightened as he read. He had always known he was created out of grief, but seeing it laid out so plainly made it feel more real, more haunting.
At the bottom of the stack was a photo of his parents—his father, Dr. Kang, standing beside his mother, Minyoung Kang. She was smiling, her hand resting gently on her husband's arm. Chan stared at the image, his mind racing. He had always wanted to know more about them, but now that he was faced with their story, it felt overwhelming.
"Chan?" Hyunjin's voice broke through his thoughts.
Chan quickly closed the folder, turning to see Hyunjin standing in the doorway. "What are you doing in here?" Hyunjin asked, his brow furrowed.
"I was helping your father," Chan replied, his voice calm but slightly strained.
Hyunjin stepped closer, noticing the folder in Chan's hands. "What's that?"
Chan hesitated, then held it out to him. "It's... more about me. About why I was created."
Hyunjin's expression softened as he took the folder, flipping through the pages. His eyes widened as he read the notes, his fingers pausing on the photo of Chan's parents. "They look... so happy," he murmured.
"They were," Chan said quietly. "At least, I think they were. But it didn't last."
Hyunjin looked up at him, his gaze filled with a mixture of sadness and determination. "This doesn't define you, Chan. You're more than what they made you to be."
"I know," Chan said softly. "But sometimes, it's hard to separate who I am from where I came from."
Hyunjin set the folder down and reached for Chan's hand, squeezing it gently. "You're you, Chan. And that's all that matters to me."
Chan felt a warmth spread through his chest, the tension easing slightly. "Thank you."
Later that evening, Chan decided to confront Dr. Hwang. The discovery of the folder had stirred too many questions, and he couldn't let them go unanswered.
"Dr. Hwang," Chan began as they sat in the study, the folder resting on the desk between them. "I found this while organizing your files. I need to know... was I really designed to be like her? My mother?"
Dr. Hwang sighed, leaning back in his chair. His face was lined with age and the weight of the past. "Yes," he admitted. "Your father couldn't let her go. She was the love of his life, and losing her... it broke him. He poured everything he had into Project Son, hoping to create a legacy for her, a continuation of the family they couldn't have."
Chan nodded, his throat tightening. "And you? Why did you help him?"
Dr. Hwang's gaze softened, and for a moment, Chan saw a flicker of vulnerability in his usually composed expression. "Because I loved her too," he said quietly. "Not the way he did, but in my own way. She was brilliant, kind, and full of life. I wanted to honor her memory, even if it meant supporting something I didn't entirely agree with."
Chan's mind raced, piecing together the fragments of his history. "Did you ever regret it? Helping him create me?"
Dr. Hwang shook his head. "No. Because you've become so much more than what we envisioned. You've proven that you're not just a project, Chan. You're a person. And you've brought happiness to people who care about you—including my son."
Chan's chest tightened, a mixture of emotions flooding through him. For so long, he had wondered if he was just a product of someone else's pain. But now, hearing these words, he began to see himself in a different light.
"Thank you," Chan said finally, his voice steady. "For telling me the truth."
Dr. Hwang nodded, a small smile on his lips. "You deserve to know."
That night, as Chan sat on the rooftop with Hyunjin, staring up at the stars, he felt a sense of clarity he hadn't felt in weeks.
"Do you think they'd be proud of me?" Chan asked softly, breaking the silence.
Hyunjin glanced at him, his expression tender. "I know they would. But you know what? I think the person you should focus on making proud is yourself."
Chan turned to him, a small smile breaking through. "I'll try."
Hyunjin leaned closer, resting his head on Chan's shoulder. "Good. Because I'm already proud of you."
And as the stars shimmered above them, Chan felt a quiet sense of peace settle over him. He still had questions, still had doubts. But with Hyunjin by his side, he knew he could face whatever came next.
