矫情的话早该烂在心里了
[jiăo qíng de huà zăo gāi làn zài xīn lĭ le]
A phrase that might be translated as 'Sentimental words would have rotted away long ago in my heart.' It conveys a sentiment of unexpressed feelings, which are now old and decayed, suggesting the user no longer believes in sharing their emotions openly.
