"Who guided me."
"Who am I and who should I trust?"
Yu Wu was guided to the abandoned building by some kind of guidance, but a voice asked her to save him.
Who is he?
Standing on the top of the building again, he actually jumped off the building himself. Yu Wu wanted to reach out and grab him, but he was dizzy and fell down.
When he woke up again, Yu Wu couldn't remember who he was. He only knew that his mission was to approach a man and lurk beside him waiting for orders.
