赢得他心便是王
[yíng dé tā xīn biàn shì wáng]
Winning his heart means becoming the king/queen, this nickname 'Win his Heart, and you Reign' reflects a deep longing and value placed upon being chosen and loved deeply by another, especially in a relationship or courtship scenario. It also might convey a competitive mindset towards winning over someone's affections, as one would reign after securing victory in contests.
