Leaf took another deep breath and slowly said to everyone:


"Actually, I had a hard time trusting all of you before now. I thought that everyone was brought here because of their connection to what happened twelve years ago, so I was very cold towards everyone, and I never even revealed my true name.

"...Something from twelve years ago?" Wei'er was startled upon hearing this and quickly asked, "Do you know about the incident from twelve years ago!?"


"Of course, I know!" Leaf nodded vigorously, "The company! Time Vibration! Eternal Life Plan! I know all about these things! Because... I've been tracking down clues about the Eternal Life Plan for all these years, so I had a pretty good guess as to why I was brought here."
