Abnormal Fluctuations

In this world, "strong emotions" such as love are regarded as deadly viruses. Everyone's heartbeat waveform is monitored in real time, and love, poetry, and musical instruments are labeled "dangerous" and sent to the incinerator.

The world seems to be at peace, with no desire, no jealousy, and no stupidity to stay up all night for anyone. But they were two fish that slipped through the net. In a world where even heartbeats are monitored, their greatest romance is watching the "abnormal" waveform on the monitoring screen that beats in sync with each other.

Three generations of people used salt grains, water patterns and bridges as code names to complete a secret relay that spanned decades.
