Tang Yu has been dreaming of a tall man who looks like him eight or nine times recently. Every time he dreams, he gets closer to the man, until finally the man who claims to be himself ten years later - Tang Qing appears in his life. They have the same experience, the same trauma, and even the same gap. But the intersection of time and space allows two selves from different periods to meet. Is there a new ending?
Intention: If no one comes to save me, then I will save myself
