The summary of the song is that he will never climb the same tree twice and repeat his mistakes. He fell in love with a girl and sacrificed for her not knowing the girl saw him as a sugar daddy , a big fish, and was only interested his money. That’s basically the theme of the song. He vowed never to be fooled again
Listen well. Like about 5 times continuously and stopping to replay. You will get more. There’s a lot in there. I wish I could tell you though. He’s actually talking about a gold digger who dreams and think about his money alone. Meanwhile he thought she was his love.
