当被你撒娇已变成习惯
[dāng bèi nĭ sā jiāo yĭ biàn chéng xí guàn]
The phrase roughly means 'when your coquettishness has become habitual'. It reflects that someone's cute or flirtatious way towards you has already formed a routine or daily habit. It shows a deep, accustomed connection with a particular person.
