Zhou Chaolai was a "locksmith".
When Jiang Hanyu was coveted, he hid Jiang Hanyu and locked his crumbling body.
Jiang Hanyu is also a "locksmith".
When he was trapped in a golden cage by Zhou Chaolai, he entangled with Zhou Chaolai in every possible way, placing the shackles of love on Zhou Chaolai's heart.
In the end, the shackles were too heavy, or maybe it was because of love.
This is the "Pujiang Lock" that can be sung endlessly.
Concept: Love is two-way.
