The Corpse Whisperer?

[Dual male leads] But not deliberately playing up a romance

[Cthulhu + cyberpunk + mythological crossover]

[Fragmented narrative across multiple volumes]

[Parallel universes]

Forensic pathologist Qi Mo encounters a supernatural phenomenon while dissecting a bizarre corpse. It suddenly vanishes before his eyes. Soon afterward, he gets a call from his college classmate Lin Xiuyuan, who tells him he can see spirits invisible to ordinary people...

And so the story begins, in a world filled with “corpse whisperers?”...

The bonus stories in the final volume feature some very bold ideas, translating the concept of the fourth dimension into assignments for high school observers in a meta-classroom.
