"Where did the burning branch come from?"
"I don't know who threw it in, I saw it about to go out, so I curiously tried it..."
"Is it because the warehouse almost burned down that you feel scared?"
Finding the source of fear is the beginning of treatment.
"No... almost burnt someone to death... I ran away..."
After Zheng Xu finished speaking, Xiao Qian fell into a brief silence, could it be...
"Do you remember who that person was?"
"I don't remember..."
At this point, things were basically clear.
Zheng Xu nearly killed someone by setting fire, then suppressed his feelings for years. People instinctively forget things with significant stimuli, so his amnesia turned into a mental illness. Now, as long as they find the unlucky guy he feels guilty about, the problem can be solved.
Since Zheng Xu didn't remember, it must be hidden deep in his heart.
