Heartstring Spectrum

Background of the times The coastal city of the near future - Neon City. Five years ago, an abnormal weather "white noise storm" across the city swept into the night sky, bringing with it a kind of shimmering particles that could only be sensed by sensitive people, known among the people as "heart dust." Since then, the emotions of a few people will be "exposed" into visible mental images (combinations of light, lines, sounds, and shadows) under extreme pressure. People who notice this phenomenon are also called "empathizers." Basic rules Each person's "psychic spectrum" tends to be different (a personality spectrum inspired by MBTI), and corresponding mental images and "mind areas" (small worlds of the soul) are formed when strong emotions occur. An unbalanced mind will attract "noise shadows" (virtual images condensed by negative emotions). They will not "kill monsters" but amplify people's misperceptions. The way to correct deviations is not to fight, but to enter the minds of others, find the "false notes" (notes of cognitive deviations) and tune them. Those who can enter must have the matching "resonance key". The core of the white noise storm five years ago was an abandoned old lighthouse on the outskirts of the city. It still glowed with a faint blue-white light at night. It is rumored that there is a "zero frequency" hidden there that causes an imbalance in collective resonance. Organizations and camps Lighthouse Office: A small studio composed of five female protagonists. On the surface, it is a "heartbeat radio station + campus/community mutual aid station". It actually provides psychological guidance and emotional adjustment. Observation Bureau: Monitors abnormal emotional events, advocates a scientific stance, and is cautious and conservative. Gray Net (underground group): spreads anonymous "emotional challenges", induces people to "prove their true selves" in extreme ways, and is suspected of collecting zero-frequency data. The Old Lighthouse: The source and end of the White Noise Storm, connecting the legend of the missing and the protagonist's past.
