The Killing Stalking meme originates from the intense psychological horror manhwa of the same name by artist Koogi, which gained a massive cult following on Lezhin Comics. Featuring the dark and twisted relationship between Yoon Bum and Oh Sangwoo, the series' haunting imagery and expressive art style became a staple for internet memes, particularly in anime and manga circles. While the source material is deeply disturbing, fans often use the templates to ironically highlight toxic behaviors, chaotic energy, or the 'I can fix him' trope. These memes typically contrast Sangwoo's charming facade with his predatory nature, making them popular for dark humor and commentary on thriller tropes.
