Channel A's 'Teachers 3: Retake War' released a teaser video containing solutions from Korean language absolute master Yoo Dae-jong ahead of its premiere on October 15.

The program is a large-scale college entrance exam survival reality show in which 100 retake students, aiming for their final CSAT attempt, undergo extreme missions and competition to determine the ultimate winner. MCs Jeon Hyun-moo, Jang Young-ran, and Mimiminu are joined by the 'God of Mathematics' Jung Seung-je, 'Korean Language Absolute Master' Yoo Dae-jong, and 'Father of English' Kim Ji-young, who come together as the 'New Teacher-vengers' to guide the contestants.

The teaser video released on the 10th begins with retake students struggling with Korean language. They expressed their anxiety and frustration about the subject, and Yoo Dae-jong offered blunt advice, saying, "It's because you haven't gone beyond that yet." He then heightened the tension by asking whether they were willing to completely change their existing study methods.

In the full-scale solution phase, Yoo Dae-jong declared, "You all met me too late. Not just one step late, but dozens of steps late," foreshadowing powerful changes. He introduced strict control measures such as a ban on conversation, confiscation of phones, and designated bedtimes, and intensively coached the retake students in a room filled with Korean language passages.

Applying pressure with the remark, "If you don't want to do it, you can leave," he later instilled hope, saying, "If you can do it, why are you trying to run away?" Although there were moments when the retake students wavered psychologically, Yoo Dae-jong smiled when change began to occur. Watching the scene, Jeon Hyun-moo, Jang Young-ran, and Mimiminu also sent their encouragement.

Yoo Dae-jong encouraged the retake students, saying, "Everyone's season can be different. It was winter at first, and next will be spring, right? Since a good spring season awaits, hang in there just a little longer."
