The two sons of the Su family are related to the vines and the wall.
The elder brother lives like a piece of jade that has been disciplined, and the younger brother's name hides his true nature - he is reckless and has amazing mobility. When I was a child, the sound of chasing after my brother and calling him "Brother" hadn't faded away. In the blink of an eye, it turned into a low "Brother, don't even think about leaving" when I locked the door.
When the boundaries of family ties were completely torn apart, Su Jinyan realized that some bonds were calamities from birth - his younger brother used bones and blood as a chain, trapping him as the only prisoner in his life.
Concept: blood ties become shackles, the ultimate pull of love and prison.
