Dungeon NPC Survival Rules (던전 NPC 생존 수칙 / Deonjeon NPC Saengjon Suchik) is a BL romance-fantasy web novel by author On Sae-rok (온새록), serializing exclusively on KakaoPage under the Delphiniue (델피니에) label — KakaoPage's imprint specializing in romance-fantasy works. The novel is listed as ongoing with 91 chapters and updates every weekday (Monday–Friday), signaling a highly consistent release schedule for a title still in its early phase.
The story runs on a unique reverse-isekai premise: a character gets trapped as an NPC inside a dungeon due to a system error, and instead of becoming a hero, must survive both the adventurers and two men competing for his attention — one a former companion with a "twisted" gaze, the other a fellow NPC who suddenly reveals possessive obsession.

The Premise: "I'm Not the Hero — I'm the NPC Trying to Survive!"
The official synopsis recorded on SSN.so opens with an absurd situation: due to a system error, Myojin (묘진) suddenly becomes an NPC in a desert-themed dungeon — a place crawling with deadly dangers. His sole focus? Survival.
Then Björn (뷔에른) appears, a former companion not seen in two months. His first words: "In a place like this, of course I couldn't find you." His gaze is somehow twisted. He declares: "Let me tell you about our relationship first. We were very close."
After Björn's arrival, Hikari (히카리) — a fellow NPC who had only ever allowed Myojin by his side — begins showing possessiveness: "Myojin. There are too many dangerous things outside." Hikari curves his eyes like crescent moons and closes the distance. "But that doesn't mean I can lock you up somewhere safe, right?"
The climax: the system announces [히카리(님)이 '반려 각인'의 대상을 지정합니다.] — "Hikari has designated the target of 'Mate Imprint'."
And Myojin? He can only stare at the two men growling at each other every time they make eye contact, thinking: Everything's fine, but… can you please stop using that ridiculous title I gave you? — Title: <제발 좀 꺼지세요> ("Please Just Get Lost").
Why This Matters
1) A fresh reverse-isekai premise
Instead of a protagonist entering a game world as a player/hero, Myojin becomes an NPC — an entity usually just a farming target for adventurers. This perspective flips the dungeon-fantasy formula and creates unique survival tension.
2) A love triangle with possessive dynamics
Two love interests — Björn the former companion with a "twisted" aura and Hikari the possessive NPC who suddenly performs a mate imprint — create intense romantic conflict. Both growl at each other every time they meet eyes, while Myojin is stuck in the middle.
3) Humor amid tension
The ridiculous title <제발 좀 꺼지세요> ("Please Just Get Lost") that Myojin gave both love interests becomes a source of light comedy amid the dark survival premise — signaling a tone that isn't too heavy.
4) Daily release schedule and large backlog
With Monday–Friday updates and 91 chapters already available, readers don't need to worry about long waits. This also signals the author's and platform's commitment to the serial's sustainability.
