我孤僻成性却念你好久我三分热度却对你如一
[wŏ gū pì chéng xìng què niàn nĭ hăo jiŭ wŏ sān fēn rè dù què duì nĭ rú yī]
This translates to 'Although I'm Eccentric and Aloof, I Have Long Missed You. Even Though I Am Fickle, I Always Treat You the Same'. It reflects mixed emotions: being introverted and inconsistent but having genuine affection for someone.
