At first glance, this song looks like a love song, and it is delicate and gentle. When Jiaju wrote this song, the lyrics she used for the first time were: It's still a rainy night staring out the window and thinking of you silently. This sentence is not suitable for a family, but it has been changed to a silent sky. The whole song expresses the sigh of dreams and some views on reality like lovers. Of course, this beautiful song can also be sung as a love song.
