只做你的皇后只做你的国王
[zhĭ zuò nĭ de huáng hòu zhĭ zuò nĭ de guó wáng]
This indicates exclusivity and deep commitment in a relationship—willingness to solely dedicate oneself to being queen (or king) for one beloved person; it portrays both romance and possessiveness as well as the grandeur associated with royalty. There may also be nuances about controlling each other in terms of relationships which need more attention.
