[Strange stories about rules + psychological breakdown + witty puzzle solving + strong settings]
The Rulebook of Emotions.
[Rule 3: Look for the client in Room 103, she knows how to escape.
[Rule 4: Don't trust any apartment resident who tries to communicate with you.
[Rule 11: Do not try to use paper and pen, the words will also be regarded as "sound" and will be obliterated by shadows.
All strange stories are just reflections of broken emotions;
All rules come from loopholes in the human heart.
Others are afraid of ghost stories, but I have insight into human nature.
The only way to "pacify" these monsters driven crazy by emotions is to actively "resonate" with them and become a part of them.
Because, to defeat the abyss, you must first become an abyss!
