Oops! Mysterious Sounds
Oops! Mysterious Sounds pairs a secondhand set of earphones with a very inconvenient gift: hearing the dead. Two rival teenagers fake-date to cover for investigating their idol friend's death, only for the case—and each other—to get uncomfortably close. It's breezy, YouTube-native Thai BL: part ghost mystery, part slow-burn romance, made for viewers who want their whodunit with butterflies attached.
If you liked this
Signal2016
A walkie-talkie connecting two detectives across decades functions almost exactly like Oops!'s earphones—a found object that turns two strangers into obsessive partners chasing an unsolved murder.
But It's a serious, occasionally bleak crime drama with zero romance—don't expect any of the flirting.
Bad Buddy2021
The platonic template for enemies forced together: two feuding neighbours pretend to date to keep their families off their backs, and predictably can't keep pretending for long.
But No mystery plot at all—pure romantic comedy, so skip it if the murder is the point for you.
Until We Meet Again2019no page yet
Thai BL soaked in the supernatural: past-life lovers, unfinished business, and the sense that death is never quite the end of a relationship—tonally close to Oops!'s ghost logic.
But Slower and dreamier than a mystery fan might want; the plot wanders more than it investigates.
The wildcard
Something you would not have found on your own.
Sorry, Wrong Number1948
Oops! runs on the same nerve: an ordinary device suddenly transmitting a voice that shouldn't exist, and the unbearable tension of being unable to warn anyone in time. This did it in 1948, on a party line, with none of the romance.
A bedridden woman overhears her own murder being plotted on a crossed telephone line and spends ninety minutes trying to get anyone to believe her—the great-grandmother of every 'device connects you to your death' thriller.
But Stagey, dialogue-heavy, and shot like the radio play it was adapted from—patience for old Hollywood required.

Girl from Nowhere2018no page yet
A gloriously nasty Thai anthology where a mysterious girl exposes the rot in Thai teen culture—idol worship, cruelty, secrets—episode by episode. Same unease, sharper teeth.
But It's horror-adjacent and morally cold where Oops! is warm—no romance, no comfort, just consequences.
Voice2017no page yet
A sound-obsessed crime thriller where a dispatcher with supernaturally sharp hearing tracks killers through audio alone—if the earphones hook intrigued you, this makes a whole show out of listening as detection.
But It's grittier and far more violent than Oops!, with none of its romance or humour to soften it.
W2016no page yet
A surgeon gets pulled through a webcomic into its world to save its hero, and the boundary between fiction and reality gets as unstable as the one between life and death in Oops!.
But The rules of its universe get increasingly convoluted, and patience for meta-fiction logic is required.
Pulse2001no page yet
Both hinge on an everyday object suddenly becoming a doorway for the dead. Pulse takes that premise dead seriously, turning connectivity itself into dread, and shows you the version of this story with all the cosiness surgically removed.
Ghosts leak into the world through phones and computers in this quietly devastating Japanese horror film, technology as haunted conduit rather than cute plot device—the same idea, stripped of warmth.
But It's slow, bleak, and genuinely unsettling rather than romantic—this will not give you butterflies at all.
Serial Experiments Lain1998
Swap earphones for a computer terminal and Oops!'s core idea—a device that shouldn't let you hear the dead, but does—becomes Lain's entire universe, played as identity-dissolving existential horror instead of teen romance.
A teenage girl gets pulled into the Wired, a networked reality where the living and the dead exchange messages freely, in this hallucinatory, philosophically knotty 90s anime classic.
But Cerebral, disorienting, and deliberately hard to follow—closer to a fever dream than a mystery with answers.
