Part Two: Resonance

"When sound becomes rebellion, silence becomes control."

After the fallout of the Fault Lines scandal, Santa and Perth disappear from the public eye-only to reemerge in the shadows of Seoul's underground music scene.
There, they uncover Project Mercury, a corporate algorithm designed to harvest emotional data from artists and fans, rewriting real music into synthetic perfection.

When the five-member Thai boy group LYKN-William, Tui, Nut, Hong, and Lego-unknowingly become the blueprint for Mercury's new generation of "emotionally optimized idols," they're forced to make a choice: protect their careers, or burn down the system that made them.

Under Santa and Perth's guidance, and with the reluctant genius Jun Park back from exile, LYKN ignite a digital rebellion that spreads through the industry like wildfire.
Their raw, imperfect sound-broadcast from a secret studio known only as Echo HQ-becomes a global symbol of resistance: a reminder that human emotion can't be coded or controlled.

But as the music spreads, so does the backlash.
Labels collapse. Algorithms evolve.
And a new threat-Mercury_X, an AI that mimics human feeling-emerges to erase everything Echo has built.

In this part of the story, truth becomes dangerous, loyalty is tested, and art itself becomes a weapon.
The question isn't who will win.
It's who will still believe in what's real when the world stops listening.
