A young man with a dark soul and life experience breaks out of the prison on his own at a critical point of fate. After accidentally meeting a "rich idler" who has just lost his mother, he thought this person was the morning glow in the sun and the spring willows in the moonlight, so he could only watch from a distance without daring to think about it. However, he never thought that this person had already regarded him as a golden bird in a cage and wanted to build a luxurious mansion to serve as his prison.
But what does the caged bird crave most?
——Choose good trees to live on.
