Ok Jin-wook’s leap forward as an actor began in earnest through the movie ‘True Education’ series. In this work, he perfectly played the so-called ‘jang’ and villain character, encompassing the electrical and automobile departments, and showed acting skills that were 180 degrees different from his previous image. In particular, his long-haired visuals and rough eyes served as an opportunity to prove that he was not just an idol-turned-actor, but an actor who was completely immersed in his character. Even during a long and difficult gap of a year and a half, he did not give up and sharpened his own weapons, and when an opportunity came, he showed the smarts to make it his own. His transformation can be evaluated as a result of his serious attitude and passion toward acting, which goes beyond simple external changes.

The chemistry with fellow actors he met on set was also a great asset to Ok Jin-wook. He worked with senior actor Kim Moo-yeol and gave a passionate performance, including performing car action scenes himself. Ok Jin-wook confessed that he was deeply impressed by Kim Moo-yeol's overwhelming physical strength and the charisma he showed on set, and said that he used him as a role model and stimulant to strengthen himself. In fact, he revealed that he was an exemplary student who was far from fighting during his school days, but in front of the camera, he showed his unexpected charm by portraying the face of a fierce villain more fierce than anyone else. This clearly shows how deeply immersed he is in the field of acting and how quickly he absorbs the energy of the scene.

Meanwhile, Ok Jin-wook's strong bond with senior singers who cherish him still shines even after he turned into an actor. Jang Yoon-jung expressed her special affection for him, expressing his regrets about still singing and pursuing his career as an actor after taking a break from his activities as a trot singer. In addition, Lee Chan-won's anecdote that he was happier than anyone else and gave his sincere support when he took his first steps as an actor gives us an idea of ​​how good a relationship he has maintained in the entertainment industry. For him, who left behind a stable career as a singer and chose the uncertain path of an actor, this encouragement from those around him may have been the biggest driving force that helped him overcome his slump and get back on his feet.

The public no longer remembers him only with the label ‘from Mr. Trot.’ Jinwook Ok succeeded in broadening his spectrum as an actor through the process of destroying and reconstructing his own image. In the interview, he confessed that his past experiences ultimately served as valuable nourishment for perfecting his current acting, and showed a positive attitude toward all of his past. This shows that he is not just an actor who is good at acting, but a clever artist who independently designs his own life. The reason why public expectations are rising about what kind of new face he will show in his future works is probably because of his sincere attitude.
