Heung-Sik’s father protected him by helping dispose of Hyang-Mi’s body, though Heung-Sik later claims he did not kill the Chinese delivery man and was framed (The Review Geek (detailed recap)).

Who is the killer in When the Camellia Blooms?

Heung-Sik is the serial killer nicknamed Joker who targets Dong-baek throughout the series (The Review Geek (detailed recap)). The killer starts by poisoning stray cats before targeting people like Hyang-Mi (KDramaLove (fan resource)). Hyang-Mi is a part-time waitress and delivery girl at Camellia murdered by the killer (KDramaLove (fan resource)).

Spoiler-free clues

The show drops subtle hints throughout: the killer is a local with mobility in Ongsan, someone with access to both the bar and the surrounding area. Yong-sik’s police instincts guide viewers toward noticing who lingers too long near Dong-baek. The early victims include stray animals — a pattern that connects to the later human killings.

Revelation and impact

The reveal in the finale satisfies because it recontextualizes earlier scenes rather than appearing from nowhere. Heung-Sik’s father helped dispose of evidence, which explains why suspicion initially fell on him. The yellow ear plug clue — found in the finale — ties back to Hyang-Mi’s murder and gives Yong-sik the breakthrough he needs (The Review Geek (detailed recap)). The emotional impact lands because viewers have invested in the characters long enough to feel the stakes.

— The Review Geek (reviewer)

These characters had endeared themselves to me, and coming back to this show consistently felt like a reunion with old friends.

— The Fangirl Verdict (reviewer)

The genre-blending approach works because the show never lets any single element dominate. Romance, mystery, and slice-of-life share equal weight, giving each storyline room to breathe without overshadowing the others.

For viewers deciding whether to commit 40 episodes, the calculus is straightforward: the show delivers a complete emotional arc with no dangling threads. The mystery resolves, the romance closes, and the secondary characters get their moments. For fans of character-driven storytelling over plot-driven spectacle, When the Camellia Blooms earns its runtime.
