Jungkook’s father had left when he was a child, abandoning him and his mother for a new life in America. Over the years, the pain of his abandonment faded into a distant ache, buried deep within him.

Years later, his mother handed him a letter. It was from his father.

“Jungkook, I’ve started a new life in America. I have another child, a daughter named Yuna. She’s at the address below. It’s your responsibility to take care of her. I can’t.”

The words hit him like a punch. How could his father ask him to clean up his mess? Yet, despite his anger, the thought of Yuna, alone and abandoned, gnawed at him.

After days of hesitation, he stood outside a rundown apartment, the letter in hand. His heart raced as he knocked on the door, uncertain of what awaited him.
