Flashback.
"Dad! When are you going to buy me the doll that I wanted?" Little Lena Park asked as she looked up at her dad.
Her dad, with a bald head despite being young, smiled at her. He was a janitor in a nearby theater in their neighborhood. He didn't make much, so it pained him to see his daughter ask for something he couldn't afford.
He had always wanted to be a performer—an idol of some sort. However, life just didn't turn out that way for him. He was blessed with his own family at a young age, so he had to let go of his dream.
With that, he opted to work in a theater so he could get close to his dream—even if it was only a little bit.
He smiled and patted Lena's head. "Don't worry, honey," he said. "Dad is working hard. I'm currently making some new cleaning products, and a lot of people are interested in buying them. Once I get back my capital, then I will buy you the doll that you want."
