我本孤僻成性却念你好久
[wŏ bĕn gū pì chéng xìng què niàn nĭ hăo jiŭ]
Translation as 'I am naturally introverted but have thought about you for a long time.' It describes a paradoxical personality trait where despite being usually solitary, there has been prolonged affection or contemplation focused specifically on a particular person or subject.
