捂着心说不疼只是烂了而已
[wŭ zhe xīn shuō bù téng zhĭ shì làn le ér yĭ]
'Covering my heart and saying it doesn't hurt just means it has deteriorated.' Here, the person feels deep-seated pain within the heart, symbolizing emotional trauma that is so profound that expressing its hurt is difficult, almost impossible, hence saying there's no hurt when really the situation is worse than expected.
