他不是月亮姐姐是太阳哥哥
[tā bù shì yuè liàng jiĕ jiĕ shì tài yáng gē gē]
This name humorously assigns celestial personalities - where he's not a lady-like moon, but instead an outgoing and warm brotherly presence represented by the sun. It conveys a message that the individual is more like a friendly, bright, and energetic sun rather than a mysterious and calm moon.
