虽然没有公主命但会存颗女王心
[suī rán méi yŏu gōng zhŭ mìng dàn huì cún kē nǚ wáng xīn]
Though I wasn't born with the destiny of a princess, I will always have the heart of a queen. The person probably believes in self-worth and having a strong and noble character even without a so-called royal background or lifestyle.
