Global media platform BoldPage recently released a group photoshoot featuring the six main actors of "Teach You a Lesson": Park Seo Yoon, Song Si An, Ok Jin Wook, Lee Bong-jun, Lee Seung-gyu, and Jang Yo-Hoon.

This photoshoot holds special significance as it brought together the rookie actors who portrayed characters caught in intense conflicts and distinct narratives within the series. While they left a strong impression on viewers with their sharp and intense characters on screen, the actors displayed tight-knit chemistry on set, filled with playful antics, comfortable rapport, and affectionate reactions toward one another.

Notably, director Hong Jong-chan, who helmed "Teach You a Lesson", and actor Kim Mu-yeol, who led the series as the title character Na Hwa-jin, made surprise appearances at the shoot, moving everyone on set.

Director Hong Jong-chan first cheered on the junior actors with a heartfelt video message. He began by saying, "I am happy that the series is doing well, but it is especially meaningful for me as a director that viewers have recognized your acting." He continued, "You all did a great job. I know how much potential each and every one of you has, so I hope you believe in yourselves."

Director Hong also promised, "Our line of work is a constant series of uncertainties. Whenever you feel anxious, tired, or exhausted, reach out to me anytime. I will watch over each of you until the end to see how much you grow."

Touched by the director's sincere words, the actors on set eventually burst into tears, responding with, "We love you," and "Thank you."

The atmosphere became even more emotional as Kim Mu-yeol joined via a surprise video call. Kim Mu-yeol offered detailed encouragement by mentioning the passionate performances of the junior actors in each episode. Starting with a greeting to Ok Jin Wook, who played Jo In-beom in episode 2, saying, "You did a great job, congratulations," he then gave a thumbs up to Jang Yo-Hoon, who played the juvenile offender Min Ji-woong in episode 6, saying, "Your energy really came through." He also showered Song Si An, who played teacher Choi Ji-seon in episode 5, with praise, saying, "Your portrayal of the character's vulnerability and the feeling of a newcomer to society made the character stand out even more."

As a senior actor, Kim Mu-yeol left a heavy yet warm piece of advice that resonated with the juniors: "Let's not give up on acting." The actors expressed deep gratitude for the unexpected appearance and sincere encouragement from the veteran actor.

The actors also expressed their deep respect for director Hong Jong-chan, who opened up infinite possibilities for them on set. One actor remarked, "The director is as comfortable to talk to as a neighbor. When we were rehearsing, he would tell us, 'Try everything you can do,' which allowed us to work with joy and passion." Lee Seung-gyu added, "The director is genuinely curious about us as people. I was grateful that he often asked questions like what kind of actor I want to become."

The bond formed within the project continued to grow stronger even after the cameras stopped rolling. The surprise support from director Hong Jong-chan and Kim Mu-yeol went beyond simple encouragement, serving as a solid pillar of support for the rookie actors who have just begun to spread their wings, proving the strong loyalty of the "Teach You a Lesson" team.
