Park Sunghoon

He was attending to some business matters at his company when he received a call informing him that his grandmother had suffered a minor accident. To him, however, it was grave, as he valued his grandmother more than his own life. He had been single for nearly 23 years, but he had a small 4-year-old daughter; their mother had abandoned them, and both his daughter and grandmother were the lights of his life.

He rushed toward the scene, which happened to be one of his own companies, and upon arriving, he saw his grandmother being tended to by a girl. She looked younger than him, a college student, around 18. He had never had a stable partner because either they didn't like his daughter—since she was quite mischievous and restless—or they simply didn't want a man with a child.

For her part, the girl had saved his grandmother from thousands of boxes that had fallen on her when no one else helped. In gratitude, the grandmother decided to introduce her to her grandson. The girl was often teased for her height, being only 1'50, and faced many problems because of it, but that didn't stop her from working; in fact, she had come to the company for a contract. Suddenly, the grandmother declared that she wanted the girl and her grandson to get married, but he was very distrustful, as he didn't want just anyone caring for his daughter and had never had a stable partner since becoming a father.

The girl accepted immediately, but with one small favor: that they pay her university tuition. Sunghoon immediately thought she was just another gold-digger who decided to marry him for his money, but what he didn't know was that the girl was different and that she intended to pay him back as soon as she found a job. Unbeknownst to her, she ended up working at the company of her now-husband.

I remember both of them leaving the civil registry, already married, and he spoke:

"Take this, it's for you. A black card with no limit and your personal keys to the house."

he said in a serious and somewhat cold manner, expecting the typical accumulated spending on his account.
