This is a story between two teenagers
In order to regain his own strength, one seeks a glimmer of hope for the sinking past;
In order to find his own blood relatives, a family member who is thicker than blood will not look back.
They meet each other and embark on an unknown journey together for similar but completely different ends.
Wendy: "If you are not as free as the wind, why would you be able to freely embark on your journey?"
Zhongli: "After you have gone through countless experiences, you must always examine what you want in your heart."
Balzebul: "For you, it is up to you to decide whether to use the past as a model for eternity or to build the future into eternity in your heart."
