我命中缺你
[wŏ mìng zhōng quē nĭ]
In Chinese culture, the concept of fate or destiny is important; therefore, a saying like 'I was born destined to have you' means that missing or lacking this certain someone would leave life incomplete or imperfect. Here, 'you are essential but missing in my destiny'. It emphasizes someone's unique role in the completeness of a human being or soul.
