O'PENing: 20th Century Ha Jun

Part of tvN's prestigious O'PENing drama project (formerly Drama Stage), '20th Century Ha Jun' tells a quirky and deeply relatable story about a man named Ha Jun who tries to approach life and romance through strict rationalism and logic. Set against the backdrop of modern Seoul, the series explores the comedic and emotional friction that occurs when mathematical precision and calculated choices collide with the unpredictable, messy nature of human emotions and love. Ha Jun believes that every human interaction can be optimized and that emotional vulnerabilities can be avoided through logical planning. However, his carefully constructed worldview is upended when he encounters a free-spirited individual who challenges his core beliefs. As they navigate misunderstandings, societal pressures, and unexpected heartaches, Ha Jun is forced to question whether a life completely devoid of emotional risk is truly worth living.
