My name is Xu Changsheng. The main symptom of a mental patient is split personality.
As for why I know I have a split personality. Quite simply, he, my alter ego, wrote me a note. The content of the note is:
[Dear Mr. Personality, good afternoon. ^-^]
It's quite arrogant, this thing.
But as time went by, I discovered that he might not be my secondary personality. It's the remnant soul that resides in me.
