Cool series
📖 Synopsis & Context
Seon Woo-hyeol (Ok Taec-yeon) is a half-vampire, half-human who’s been trying to become fully human for centuries. He attempts to complete his transformation by sleeping in a coffin for 100 years, but is accidentally awakened one day early by Joo In-hae (Won Ji-an), a cold and practical nurse who inherited his mansion. This sparks a forced cohabitation, a romantic entanglement, and a journey of self-discovery.
🎭 Acting
Ok Taec-yeon shines in a very different role from his villainous character in Vincenzo. He blends humor, old-world charm, and vulnerability, making Woo-hyeol a memorable character.
Won Ji-an delivers a solid female lead performance. She begins as cold and self-sufficient but slowly reveals a deeper emotional side. She even won the Excellence Award at the KBS Drama Awards for this role.
😄 Comedy & Chemistry
The comedy is one of the show’s strongest aspects: Woo-hyeol is amazed by modern technology—like kiosks and smartphones—and his reactions are genuinely funny.
His relationship with In-hae evolves naturally from antagonism to romance, with good chemistry and clever interactions.
🧩 Strengths
Fresh take on the genre: A vampire drama that leans more into comedy and romance than horror or action.
Well-rounded characters: Both leads and supporting characters (like Do-sik and Hae-won) are given emotional depth.
⚠️ Weaknesses
The second half loses momentum, becoming overly melodramatic and somewhat disconnected; certain plot resolutions feel forced.
The ending especially divided viewers—many found it disappointing, abrupt, or inconsistent with the tone of the earlier episodes.
Reddit Reactions
“The ending is disappointing, and there’s a lot of WTF moments.”
“The finale ruined everything… HEARTBREAK 💔”
Still, some viewers enjoyed its quirky tone:
“It’s silly and funny... just fun and will make you laugh.”
