Mu Yu, the protagonist, is chosen by a "Chuunibyou System" that claims to cater to his middle-school syndrome tendencies. However, the system has ulterior motives: it manipulates him into becoming an irresistible heartthrob.
But Mu Yu has no interest in romance and loathes receiving affection. He just wants to retreat to his comfort zone. Unfortunately, the male leads in every world refuse to let him go, instead clinging to him like shadows, vying for his attention.
World One:
As a famous virtual streamer, Akka the "little demon" is exposed as a playboy, simultaneously involved with multiple men. In reality, however, he's just a sloppy, unhygienic shut-in with a tarnished reputation.
Mu Yu assumes his scandals will drive away his admirers, but instead, they fight over him.
From a warm, doting "housewife" to a skilled hacker, clingy puppy-like lovers, and aloof protagonists, all are determined to be with him forever.
Mu Yu: "Thanks, but I’m moving on to the next world."
World Two:
In a world of hypnosis, Mu Yu becomes a notorious "yellow-haired delinquent" destined for a grim end. But when the protagonist's harem clings to him instead of the main lead, things take an unexpected turn.
Themes:
Quick Transmigration: Mu Yu travels across worlds, each with unique challenges.
Reverse Harem: All characters are inexplicably drawn to Mu Yu.
Humor and Satire: Parodies common tropes in BL, particularly around irresistible protagonists.
Non-Romantic Undertone: Mu Yu actively rejects romantic advances, despite his popularity.
Tagline: "I never wanted to be a heartthrob, but here we are."
