Wang Lujie: When I Came, I Was Still Young.

[Explanation on the cover: When you come, the child will meet the boy again] Purely fictitious~ [There will be no training materials or anything like that! [New world view] He passed by someone's childhood. Wiped his tears, coaxed him to sleep, and gave him the morning and evening of three years. Later, he returned to his own timeline, and the boy standing there had grown up. The man looked at him and never remembered his childhood. It doesn't matter. He thought. What you have forgotten, I will remember for you. [There may be other guest appearances from Xiaosisi]
