On September 30, tvN's upcoming drama 'Melancholia' released the 1st teaser video ahead of its November premiere. 

In the teaser video, Ji Yoon Soo (played by Im Soo Jung) and Baek Seung Yoo (played by Lee Do Hyun) walk together side by side under the warm sunlight. Each step and hand movement are measured using a mathematical formula, but there is a warm, comforting atmosphere between the two characters as they communicate through the study of mathematics.

'Melancholia' is a drama that depicts the story of a math teacher and a math genius, who make efforts to break the existing prejudice and corruption in their private high school. Many look forward to the on-screen chemistry of veteran actress Im Soo Jung and rising actor Lee Do Hyun.

'Melancholia' will premiere on November 3 at 10:30PM KST.
