Tensions arise between the characters of Choi Woo-shik and Son Suk-ku in the crime thriller series "A Killer Paradox," which is set to stream on Netflix beginning Feb. 9.

Based on an award-winning webtoon of the same title, "A Killer Paradox" is about Lee Tang (Choi), a university student who becomes a murderer and becomes the subject of pursuit by detective Jang Nan-gam (Son).

The streamer released Thursday a teaser for the series, showing a man attacking Lee, who retaliates by hammering him, apparently resulting in the former's death.
