"Guo" refers to the past, passing, and the helpless fate of Bai Yichuan; "Island" is an isolated island in the sea, symbolizing the paranoid Bai Jianshen; Yang Zhiyu is an erratic and unstable bridge, but it connects the past and the isolated island. Guoyu Island is another island that will not appear at any time but will always exist. They made an agreement: "No matter how big the storms are in life, or how many times we experience the ups and downs, we will always be there for each other and never leave each other, just like that 'crossing' island."
A little sweet drama. Hope you all like it.
