When he woke up, he forgot everything. He was rescued from drowning, but found that he was very familiar with the rescuer's family. Who is he? Why is he alive? Where does this familiarity come from? Can his lost memories tell him? As time passed, the mysteries continued to be revealed, and the reversals continued to unfold, he was shocked to realize his past and identity. Many years later, he stood alone on the top of the clouds. The things he pursued so hard were now at his fingertips, but no one was with him anymore. "Perhaps I am wrong." "I still hope that I never know. In this way, I will not meet you, and I will not cause more troubles." "The matter has reached this point, and there are too many involved, and no one can escape." "Dawn is coming." Meeting you accidentally on a different road is a mistake. Who knows that fate will play tricks on you, and you will be entangled for the rest of your life.
