我若不狠谁替我痛
[wŏ ruò bù hĕn shéi tì wŏ tòng]
Literally translated as 'If I'm not ruthless, then who will feel my pain for me.' It shows that the owner is prepared to be tough or even heartless in order to avoid further emotional turmoil. Sometimes, it also indicates self-protection from hurtful relationships by hardening one’s heart.
