我宁愿做一个冰冷的烂人
[wŏ níng yuàn zuò yī gè bīng lĕng de làn rén]
A rather melancholic or negative way of expressing dissatisfaction with society or personal situation. Literally translating to preferring to be an icy cold rotten person implies they would prefer to remain emotionally guarded, perhaps having been hurt before and finding this stance protective.
