Son Na-eun on So Ji-seop's pure gold gift to the cast and crew of 'Kim Bu-jang'

Son Na-eun had no idea what was in the package.

"When I first received it through my manager, I thought 'What is this?'" she said of the pure gold So Ji-seop gifted to every cast member and staff on SBS's Kim Bu-jang. "I couldn't even imagine it would be pure gold."

The drama follows an ordinary father, Kim Bu-jang (So Ji-seop), who becomes the most dangerous man in the world to get his only daughter back. Written by Nam Dae-joong and directed by Lee Seung-young, it opened at 9.5% viewership (Nielsen Korea), crossed 20% by episode four, and closed at 23%.

Son Na-eun played Jung Sang-a, a deputy at Sangsaeng Savings Bank. She took on action sequences for the first time in her career. Director Lee Seung-young apparently told her she would become "an incredible action actress," and word spread on set that she was good at it. "So I thought I should work even harder," she said.

On So Ji-seop's gesture: "The sincerity of how he carefully looked after not only the actors but all the staff was truly felt, and I was so grateful."

The interview took place July 29 at a café in Cheongdam-dong, Gangnam-gu, Seoul.

A reward vacation is now confirmed for So Ji-seop, Yoon Kyung-ho, Joo Sang-wook, and Son Na-eun. Choi Tae-hoon will not attend due to scheduling conflicts. The cast rarely had time to talk during filming, at the wrap dinner, or at the finale broadcast. The trip is the first real chance for the group to connect properly.
