In Love and Deep Water

Suguru Ubukata (Ryo Yoshizawa) is a butler on a luxury cruise ship, loyal to the people he serves and careful never to put a foot wrong. When a murder happens on board while the ship is at sea, he crosses paths with Chizuru Banjaku (Aoi Miyazaki), a mysterious woman who is also trying to find out what happened. Yusuke Taki sets the mystery among the ship's wealthy passengers, and Suguru stands in his butler's uniform on the deck, still polite, still watching.
