Han Woo Joo’s Character Profile

Han Woo Joo (Kang Seung Yoon)

| Bimo Province Police Agency’s Golden Time Team Member

A 4D patrol officer that was specially recruited to be a cyber team member!

Hailing from three generations of engineers, he’s been in the spotlight for having incredible intellect. However, rumour has it that he abandoned his PhD studies as he valued a work-life balance.

He first felt the fun of cyber investigation as he solved a case of illegal distribution of adult webtoons with just one finger. But no matter how serious a case is, he makes sure to always leave the office on time.

He’s the final boss of being an individualist/free spirit…

After joining the Golden Time team and listening to the desperate pleas of the victims, he realises for the first time the sense of duty he has to have to be a real police officer. This 4D character is in a dilemna over how to get a sense of duty he doesn’t have.
