I recently watched the South Korean action-school drama Teach You a Lesson (Korean: 참교육). It's a recent hit series on Netflix that focuses on school life and education, and I found it to be a very engaging and well-made show.

Interestingly, toward the end of the series, Telegram is portrayed as a communication platform used by students involved in drug trafficking. It's somewhat ironic to see that even 🇰🇷 South Korean media portrays #Telegram as a major hub for drug-related activities.

The series has also become popular in many countries around the world.
