Pop Star Rising

Lament! The genius young songwriter Jasper Quinn died after getting into a car accident!
As the world grieved his loss, Jasper found that he had transmigrated into a BL novel. A strange voice rang inside his head.

[Greetings, Jasper Quinn. You have been chosen by our organization to complete a special mission. Kill the protagonist shou*. If you refuse, your soul will be terminated. If you fail in your mission, your soul will be terminated. Do you accept?]

So it was either do or die? Jasper pondered for a few seconds before accepting.

Finding himself in the body of a canon fodder character with the same name as him, Jasper gazed at his face and listened to the extraordinary voice that came out of his throat. He realized he could finally fulfill the dream that had once been only a distant fantasy - becoming a Pop Star.
