Korean dramas are the recent obsession for Indian viewers. Now, a new K-drama named Undercover High School is making quite a buzz among K-drama lovers. The teaser of the show was recently released, and it has reminded fans of Shah Rukh Khan's iconic film Main Hoon Na.

The teaser introduces Jung Hae-sung (Seo Kang-joon), a National Intelligence Service (NIS) agent, who ends up in a high school after being demoted from his position. This plot is quite similar to that of Main Hoon Na.
