你说过好好陪我走下去我说过好好陪你走下去
[nĭ shuō guò hăo hăo péi wŏ zŏu xià qù wŏ shuō guò hăo hăo péi nĭ zŏu xià qù]
'You promised to walk with me; I promised to walk with you.' It implies mutual promises of companionship, support, and shared struggles or journeys in life. This could refer to romantic love, friendship, or even a partnership between people who deeply care for each other.
