冷淡的你我早已沉默如今的我也不想多说
[lĕng dàn de nĭ wŏ zăo yĭ chén mò rú jīn de wŏ yĕ bù xiăng duō shuō]
The nickname reflects a gradual cooling down of affection towards someone. Initially, there was silence out of indifference, but now they simply don't feel much need to talk more about it, signifying a complete lack of interest and giving up.
