In Our Prime

In Our Prime (2022) is a Korean drama you can watch online on iFILM. A quiet, withdrawn school janitor hides a buried past: he was once a brilliant mathematician who defected from North Korea to the South, and he guards his secret as carefully as the building.

Ji-woo attends an elite private school but drifts at the bottom of his class, with math his worst subject. A chance encounter with the silent janitor turns into lessons that reach far beyond equations. The aging defector slowly relearns how to trust people, while the teenager starts to see numbers as something beautiful rather than a punishment. Choi Min-sik leads the film, directed by Park Dong-hun, running 117 minutes.

The movie sidesteps the usual mentor-story fireworks — there's no last-minute math-olympiad triumph, just two lonely people who gradually come to need each other. A warm, low-key drama for anyone who loves stories about teachers and students. Stream In Our Prime (2022) online on iFILM.
