Hi there, I would like to know about this sentence: what does 不甘心 mean there? 不甘心的他打算先行逃走. If a context is needed, there is this sentence right before. 却没想最终自己反倒被一直轻视小看的美铃最强的一刀给打成了重伤，懒惰整个头部被切成两半，妹妹所在的那部分义体直接消失了. 不甘心的他打算先行逃走, 却遭到了栞的拦截，最终被栞所击败。 Does it mean "hurt" or something? Thanks for your answers. (that's from a visual novel, where the character shares a body with his sister for fight. 栞 and 美铃 are names of others characters).
