Who Doesn't Like a Pretty Green Tea?

Ruan Hua once thought she was a lucky Cinderella. She wasn't. She was actually a mermaid. When dawn came, the mermaid left the stage, and the prince and princess were married. Fish: "Congratulations on your wedding." But the princess wasn't satisfied and insisted the mermaid turn into sea foam. ??? A friendly reminder: The heroine is stunningly beautiful, has a flexible sense of right and wrong, but is a model citizen. She falls in love at different points, has plenty of one-sided crushes, doesn't marry (?) or have children (√), and stays young forever. Theme: Make every day a happy one!
