Unfortunately, Xu Yuan transmigrated into a horror survival game world.
Even more unfortunately, the game required players to find fragments of songs, decipher the lyrics, and perform the complete songs to clear each stage. Xu Yuan was famously so tone-deaf that his singing could kill.
Even more unfortunate than that: Zhu Fu, born into a musical family, a professional singer since age fifteen, and the lifelong nemesis Xu Yuan had known since childhood, had entered the game too.
During a certain stage, a question for the System
“Is there a dead person in the song?”
[Yes.]
“Does the killer's name appear in the lyrics?”
[Yes and no.]
Xu Yuan frowned at the lyrics and muttered thoughtfully, “Could it be that someone's feelings have turned sour?”
The System, of course, didn't answer. But to his surprise, his nemesis spoke beside him:
“Yes.”
Xu Yuan: ?
After that, Xu Yuan realized that the way his nemesis looked at him was even scarier than a ghost...
Note: This is a traditional horror survival game story with no supernatural powers, relying purely on brains. The protagonist is tone-deaf just for cuteness (*  ̄3)(ε ̄ *), and it won't keep him from clearing the game~
