In 2046, the virtual world "Arena" is the battlefield of fate for all 16-year-old citizens.
Lu Shen has a secret - he can hear the heartbeats of others.
Not a metaphor. Really heard it.
Fear, excitement, greed, love... All emotions were sounds in his ears.
The system said he was "Interventionist No. 404" - A non-existent error.
But he is not wrong.
He is the only one who can hear the truth.
And the last voice he heard came from a girl who shouldn't exist:
"You're here."
