伤得最深的是最初的真感情
[shāng dé zuì shēn de shì zuì chū de zhēn găn qíng]
The meaning behind the idiom-like expression in the Chinese language '伤害的最深是最初的真情' translates to the 'Deepest hurts come from our truest feelings initially.' This sentence signifies the pain coming from sincere initial emotions when faced by betrayals from close relations which leaves deep hurt and regret over the past sincerity given whole-heartedly.
