Lu Yushen, the president of the Astronomical Society, had a lifelong obsession with deciphering a deep space melody that had lasted for fifty years - a mystery that his father had not solved even before his death, and the reason why he was ridiculed by the academic community.
Until the school anniversary night, the impromptu movement played by transfer student Jiang Yu on the piano matched perfectly with the "alien last words" in his database.
"This song? I dreamed of it last night." The boy smiled carelessly.
The global astronomical community was shocked by this, and a mysterious organization quietly sneaked into the campus. Lu Yushen had to bind himself to this seemingly unorganized "Chosen One" and protect this universe-level secret amidst surveillance and crisis.
When all the evidence points to the truth about civilization behind the melody, the two are forced to stand at a crossroads of choice: should they hand over this precious "signal source" and complete the scientific mission; or should they escape together and use an unprecedented ensemble to send a response that belongs to mankind—and each other—to deep space?
Purpose: To explore the most intimate human emotional connection on the vastest scale of the universe, and prove that the two are essentially the same: they are both a struggle against loneliness, a desire for resonance, and a brave response to the meaning of existence.
