我可以沒心沒肺
[wŏ kĕ yĭ méi xīn méi fèi]
'I Can Be Heartless and Ruthless' indicates someone who may choose to be detached emotionally or believes in handling life's ups and downs by being less sensitive. This doesn't always mean they truly lack feelings, but prefer showing resilience and a carefree attitude in face of adversity.
