According to an article in Drama Fever, he recently took a stress-relief vacation by visiting Tokyo.
He backpacked and stayed in a capsule hotel, (kapsule hotelru in Japanese,) where people are essentially pigeonholed in units stacked up like person-sized container boxes.
As Roy can certainly afford a suite at any luxury hotel, the reason that he stayed in the capsule hotel was quite a surprise to everyone: he's afraid of ghosts.
He said, "Do not stay in a room that's at the end. Knock on the door before you enter, and step inside with the left foot first."
His fear of ghosts is so severe that he has even turned down several new films involving ghosts or scary plots.
