Director: Yusuke Taki
On board a luxury liner adrift somewhere at sea, a devoted butler and a stranger with secrets of her own start untangling a death no one wants investigated.
What is In Love And Deep Water about?
The setting is closed off completely: a floating hotel, days from any port, where the wealthy passengers keep their routines even as something has gone badly wrong belowdecks. A veteran butler who prides himself on discretion finds his careful order disrupted the moment a guest turns up dead, and the only person willing to ask real questions is a woman he barely knows, whose reasons for being aboard don't quite add up. Together they trade favors, half-truths, and stolen moments between shifts to work out who had motive, who had opportunity, and who is quietly steering the investigation away from themselves. Along the way what starts as a professional partnership tips gradually into something warmer, complicating loyalties the butler thought were settled long before the ship ever left harbor. Director Yusuke Taki keeps the tone light enough for comedy even as the mystery tightens, letting the cruise ship's glossy corridors hide more than one kind of secret.
Cast & crew
Ryo Yoshizawa plays the meticulous butler at the story's center, opposite Aoi Miyazaki as the enigmatic woman who pulls him into the case; Rinko Kikuchi, Kento Nagayama, and Yoh Yoshida round out the ship's cast of passengers and crew, several of whom have more to hide than they let on.
Context & significance
Adapted for the screen from a serialized Japanese novel, the story leans into the closed-room mystery tradition — a finite cast, a ship no one can leave, and a detective pairing whose chemistry is meant to be as central as the puzzle itself.
