没能力保护你别怕我来守你
[méi néng lì băo hù nĭ bié pà wŏ lái shŏu nĭ]
This translates as 'If incapable of protecting you, don't worry, I'm here watching over you,' showing deep-seated protectiveness and readiness to stand beside someone precious no matter what challenges arise, despite self-perceived inadequacies.
