"Future Machine City" released the episode MV "Stars in the Corner", which was written and sung by Yuan Liyuan, a talented singer from the mainland. The slow lyric melody and Yuan Liyuan's affectionate and mellow voice complement each other, and the touching friendship between Su Xiaomai, the protagonist of the film, and Robot 7723 is expressed.

"Leave me in a dark corner and cry." The lyrics of "The Star in the Corner" sang the inner portrayal of the lonely girl Su Xiaomai. The father who left home, the depressed mother, the childhood who was ridiculed and isolated, all kinds of life seemed to push her into a dark corner, and no one cared. The appearance of 7723 is like "the sun rises again" for Su Wheat. Illuminated her life and made her feel love and warmth again. For robot 7723, Su Xiaomai is the first person it sees when it opens its eyes, like the light that it suddenly sees after a long night, which is the star it wants to guard and follow. The meeting of two tiny lives illuminates each other and presents a touching story for us.
