“Some debts outlive death; hospitality does too.”

 The Blue Moon reopens above neon Seoul, doors creaking for souls with unfinished stories. The new proprietor (Kim Soo‑hyun) keeps a perfect ledger—until an eclipse freezes the city for seven minutes and Jang Man‑wol (IU) returns, not as owner, but as the one guest the hotel cannot check out. Quick cuts: an elevator stopping at 13F: Memories; a bridal veil drifting down a stairwell with no bride; tea that shows your last regret; a ferry of coins crossing fog on the Han; the moon tree blooming with firefly souls. Rules bend—no living guests—when a lost child knocks at midnight and a grim auditor demands payment in lifetimes. Final beat: two signs flicker—Del Luna. Blue Moon.—as the clock strikes 00:00 twice.

 Review: Opulent, romantic, and eerily tender. IU’s velvet bite and Kim Soo‑hyun’s cool magnetism promise swoon and shiver in equal measure—gorgeous color, sly humor, and grief that glows.
