Walking around the D Life Park, you will find that there is no trace of Building 28. There is a bottomless artificial pond between Building 27 and Building 29. There are rumors in the school that Building 28 has always existed, but the people who say these things have never seen it with their own eyes, and most of them are spreading rumors. Over time, everyone gradually ignored this problem and just assumed that they did not pay attention when the park was built, leaving such an innocuous flaw.
Most students in University D think so, of course, excluding those who live in Building 28.
Yin Yang is one of them...
