This story is adapted from some real events and runs through a jumping timeline. It mainly tells the story of what happened after the male protagonist met the female protagonist through the Internet. The story is relatively tragic. The male protagonist's family and daughter died in an accidental car accident. The male protagonist committed suicide abroad due to depression many years later. Many of the scenes described in the overview belong to real places. Although some places have been sealed and cannot be opened to the public, the author still misses those places very much.
