Actor Yook Sung-jae is set to return to the small screen as a "sunshine intern" who disarms viewers with his charm.

The production team for SBS's new Wednesday-Thursday drama "Nine-to-Six" (written by Choi Ji-oh, directed by Lee Hyung-min and Oh Song-hee), which is set to premiere at 9:00 p.m. on Wednesday, November 25, released stills on October 23 showing Han Sun-woo (played by Yook Sung-jae) making his first commute to the legal team of Chronic Motors.

"Nine-to-Six" is an on-off work-life balance romance drama about a rational woman who has lived by proving herself through work, meeting a warm and emotional man as they rewrite their standards for work, love, and happiness.

Han Sun-woo, played by Yook Sung-jae, is a law school graduate who pursued his passions to work as a jewelry designer before joining the legal team of the automobile company Chronic Motors due to unexpected circumstances. With his innate warmth and signature bright energy, he is expected to rank number one in company-wide likability.

In the released photos, Yook Sung-jae completes the ultimate rookie look with a neat navy suit and a backpack. Instead of the tension typically associated with a first day on the job, he flashes a sunshine smile full of anticipation, making fans' hearts flutter.

Returning to SBS about a year after the drama "Gwigung", Yook Sung-jae is expected to showcase the diverse charms of a "reliable, stable younger man" through even more mature emotional acting in this new project.

SBS's new Wednesday-Thursday drama "Nine-to-Six", which will warmly color the end of the year, will premiere at 9:00 p.m. on Wednesday, November 25.
