Finally, Yongsook has a day to relax with his sons. Well, relax is an understatement... He's more likely to be running around the park chasing them as they enjoy the moment of their lives. Of course, he'll be more than happy to spend the day with his beloved twins.

Chongsu is the most energetic of the three. His messy hair is just like his father's, but his light blue eyes are like his mother's, who left them two years ago. Chongsu never shows weakness, and he is brave and courageous. He always stands up for Changmin. Chongsu is straightforward, and if he doesn't like something, he says so directly.

Although Changmin looks exactly like his twin brother, he has a completely different personality. He's a gentle and kind child. He tries not to fight with anyone, because he doesn't like it. And to be honest, he misses his mother's love.

Yongsook was a fair and strict father. He was cold and calm, and always won arguments. If necessary, he would resort to fighting if it meant protecting himself or his loved ones. Yongsook was always busy with his work as a CEO and didn't spend much time with his twin sons. However, he did everything he could to ensure that they grew up to be nice people. They had everything they needed, but Yongsook didn't spoil them too much to prevent them from becoming spoiled brats who relied on their father.

And so, as the three of them stood in front of the ticket counter, and Yongsook tried to buy the tickets, something went wrong. The payment didn't go through. Yongsook raised an eyebrow at the man who was handing out the tickets, waiting for an explanation.

"Ah... the payment didn't go through because the terminal seems to be malfunctioning... Cash only."

the man muttered awkwardly. Yongsook sighed, realizing that he didn't have any cash. The ATM was very far from the park, and he wouldn't have enough time, considering the traffic.

Changmin looked at his father and pouted in disappointment.

"Not today? Again?"

he asked in a quiet tone, disappointed that their trip to the amusement park had been cut short for the tenth time. Chongsu frowned at his father.

"Dad, are you sure you can't do anything? Maybe we should go to another park?"

Yongsook stood there, thinking, looking at the map and then at his children. He didn't want to disappoint them again. He didn't want to be a bad father, but what could he do if the terminal wasn't working? Irritation was building up slightly in him.
