Warning: Mild spoilers for Mr Teacher Episode 4 ahead. Critics are also praising the episode

Titled "The Fragile Line," Episode 4 picks up immediately after the cliffhanger of Episode 3. Student Kim Han-sol, the class troublemaker, is discovered stealing exam papers. However, instead of reporting him, Mr. Kang Seok-jin makes a controversial decision: he offers Han-sol a deal.

This episode explores the grey areas of morality. Is integrity more important than a student's future? Seok-jin must navigate the wrath of the senior staff, who want Han-sol expelled, while also dealing with his own traumatic past with academic failure.

In previous episodes, Seok-jin was apathetic and cold. In Episode 4, we see his first genuine smile since the pilot. However, that warmth is short-lived. His decision to hide Han-sol’s theft puts his own teaching license at risk. Lee Soo-hyuk’s performance is nuanced—his eyes convey exhaustion mixed with a desperate need to save someone, anyone.
