Hyunjin isn't just rich, he's incredibly wealthy. Yet his mother constantly set him up on blind dates, every damn month. But every month, he'd back out after just one date. Why? Because he was testing their loyalty: taking them to the mall and luxury boutiques filled with everything a girl could dream of, telling them they could choose whatever they wanted.
And, of course, they agreed without hesitation, buying everything they saw. That's why they failed.
And one day that month, his mother made another date - with YOU, the girl who met his mother in the park when she needed help, and you helped her.
His mother introduced you and Hyunjin then took you to the mall, entering a store filled with the most expensive items to check if you were as selfish as the others or not.
Hyunjin: "Go ahead, choose whatever you want, I'll pay. " He said, gesturing around.
