Why do oranges play games naked in the Sun Hotel?

Many viewers are attracted by the image of "orange" in the film. This character is clever and beautiful in appearance, lovely in personality, simple and full of fantasy. Playing games with bare arms and wearing cute clothes is an optimist and definitely an "otaku" killer.

The city that never sleeps tells that Shi Yue, the hotel manager, took a day off on the eve of his promotion to the head office. He and his wife Orange went to the hotel where he was about to leave, that is, the hotel where the sun never sets, for a one-day star-watching tour.
