Additional Info.

​"While the movie adaptation stayed faithful to the original webtoon’s main storyline, some scenes and character settings were altered or omitted to fit the runtime. For instance, in the original, Seo Soo-hyuk is a double agent working for the National Intelligence Service. In the movie, his character was changed to a former special agent from Unit 5446. Additionally, the depth of relationships between characters like Won Ryu-hwan, Lee Hae-rang, and Lee Hae-jin was less explored, leaving fans of the webtoon somewhat disappointed. Despite these changes, Secretly, Greatly gained immense popularity, winning the Minister’s Award in the cartoon category at the 2011 Korea Content Awards. It was later adapted into a movie, novel, and musical, further demonstrating its broad appeal. "​
