Is Under The Same Roof Based On A Novel Or Manga?

If you’re asking whether 'Under the Same Roof' was lifted from a novel or manga, the quick reality is that it wasn’t. I checked the typical tells: the opening or closing credits, production notes, and the press kit language—none of them list a source novel or manga. Instead, the project is presented as an original screenplay, meaning the story was created specifically for the screen rather than adapted from another medium.

That doesn’t mean it’s not inspired by existing themes or real-life experiences—writers often mention life events, news stories, or cultural observations as their starting point—but there’s no formal literary or comic source behind this title. For folks who like to compare adaptations, this one reads and plays like something designed for visual beats from the ground up. I found that satisfying, honestly; it feels like the creators were focused on making scenes that land cinematically, and that direct approach worked for me.

This one had me curious, so I dug through the credits, press blurbs, and a few interviews to be sure. For the version most people mean when they ask about 'Under the Same Roof'—the recent screen production that popped up in conversations online—it's not adapted from a novel or a manga. The on-screen credits and official festival/program descriptions list it as an original screenplay, with writers credited directly for the script rather than a “based on” credit. That little line in the closing credits is the fastest smoking gun: if a film or show adapts a book or comic you'll almost always see 'based on the novel by' or 'based on the manga by' there, and that simply isn't present for this title.

It's worth noting that titles like 'Under the Same Roof' are pretty generic, so confusion is understandable. There are multiple works across languages and mediums with similar names—romcom novels, stage plays, and unrelated TV episodes—so sometimes people conflate them. When tracking these down I cross-check release notes, official production company pages, and festival program write-ups. For this specific screen project, interviews with the director and writer framed it as a story conceived for the screen, born out of observations about family dynamics and shared living spaces rather than a literary source. That creative origin tends to shape the pacing and structure in a different way than most adaptations do: it feels written to hit beats visually and in sequences tailored for film/TV.

If you're the kind of person who loves digging further, looking up the production notes or the writer’s own social posts usually seals the deal; they often say 'original screenplay' or explain inspiration without naming a prior book or manga. Personally, I like original screen stories because they take full advantage of visual storytelling—'Under the Same Roof' felt crisp and cinematic in how it handled small domestic moments, and knowing it started on the page as a script makes sense to my eye.
