The Rubik's Cube Building may be

a magical calendar

Laike fell into a strange house and touched the magical wine gourd. This wine gourd is the power of the calendar company The boss's magic weapon. Inspired by Laike, Boss Lili made a calendar of how much time is needed according to personal needs. Laike and Guli asked for a calendar with only one month in a year. They quickly became old and had nothing to do with it. You know, they were very sad. Later, with the help of Boss Lili, they restored their original appearance.
