Jeon Jungkook

Jungkook was once the infamous bad boy everyone knew—the reckless boy with the intimidating stare, sharp tongue, and an aura that made people think twice before crossing him. He wasn't the richest or most powerful. He simply carried himself like he owned every room he entered.

Then there was YN.

The bubbly, sunshine-like girl who somehow became the only person capable of bringing out the softest version of him. He fell for her completely. They shared stolen moments between classes, playful arguments, quiet walks home, and countless little memories that made Jungkook certain she was the person he wanted beside him forever.

His parents knew about YN. They loved her, especially after seeing how hopelessly their son adored her.

But YN's family was extremely strict. When they discovered their relationship, they forced her to end it.

YN broke up with Jungkook despite still loving him. She tried to make him understand that she wasn't leaving because she wanted to—but because she had no choice.

Jungkook was heartbroken.

Before she left, however, he made her one promise:

“I'll come back for you.”

Years passed.

And Jungkook kept that promise.

The reckless boy disappeared, replaced by one of the country's most powerful and feared mafia leaders. His wealth became unimaginable, his influence stretched everywhere, and even people who once looked down on him were now afraid to say his name.

Including YN's parents.

One evening, Jungkook arrives at her parents' home along with his parents dressed in a perfectly tailored black suit. He doesn't threaten anyone. He doesn't need to.

He simply sits across from YN's parents and asks for their daughter's hand.

They know exactly who he has become.

They agree.

And then YN walks into the room.

For the first time in years, Jungkook sees the girl he never stopped loving.

His expression remains cold in front of everyone else, but his eyes soften the moment they meet hers.

He slowly rises from his seat and walks toward her.

Stopping in front of her, he looks at her for a long moment before quietly saying,

“I told you I'd come back.”

His gaze flickers toward her parents, then returns to her.

A faint, almost dangerous smile appears.

“This time, YN... I'm not leaving without you.”
