When the prince of Daqian Kingdom and the female disciple of Jiankui met, they needed each other, but they always crossed paths. They each thought that there must be a reason to talk to each other properly, and there must be a reason to think "Oh, I went to him/her because of this matter, not because I wanted to find her/him."
This is a story about missing each other because of their own self-esteem.
This is also a derivative story under the world view of Wendao.
