Ju Mang smiled and said,
"Look, that's how it is. It's just that this never actually happened, so your reaction is quite normal. Zero, on the other hand, wasn't so lucky."
"What do you mean?"
"Xi He once wrote some diaries, detailing the things he did to Zero. Considering that I might need to help Zero suppress other emotions later on, the idea was to control the child's emotions through surgery and, therefore, control him. That's why I've read that diary too."
"He, of all people, would write a diary?"
"Yes, you've pinpointed the crux of the matter. That diary is actually a bell to awaken memories. To put it plainly, it's the key to unlocking emotional suppression or rather, catalyzing Zero to recall his past. So, it was essentially written for Zero. Xi He did care deeply for Zero, seeing him as a child with even more potential than Akasi."
"What's written in the diary?"
"A good girl like you wouldn't want to know. As I said, Xi He and I, we are very cruel people."
