Startover means to start over.
The words of this pure music accessory: Is this wine? This is not wine, this is a river with temperature, this is muddy water that I have waded in, this is good medicine in bleak days, this is the accumulation of countless thoughts, this is countless unspeakable bitterness and grievances that I forced myself to swallow, and this is you flowing in my blood that I can't quit.
