“Some goodbyes are doorways. Knock gently; the past answers.”

 Seoul’s first snow falls out of season as the moon‑tree rustles awake. The Del Luna sign flickers, and a new proprietor (Kim Soo‑hyun)—smile like a secret—opens the lobby for souls with unfinished stories. A whisper rides the night wind: Jang Man‑wol (IU). Trailer shards: the elevator stopping at a 13th floor that shouldn’t exist; a ledger writing names by itself; a waltz with guests who cast no reflections; foxfire along a rooftop; a teacup filling from thin air; doors that open onto yesterdays you swore you forgot. He bargains with fate; she bargains with herself. To free the hotel at last, they must settle a debt older than the moonlight that owns them both.

 Verdict: Lush, melancholy, and spell‑bright—baroque visuals, sly humor, and heart‑twisting chemistry promise a swoonworthy, ghost‑lit return.
