Is A Secret Marriage... That He Won'T Stop Talking About Canon?

Let me clear up the canon status of 'A Secret Marriage... That He Won't Stop Talking About'—it's a bit of a mixed bag, but there is a clear way to think about it if you want to be precise. The simplest truth is this: the original serialized work (usually the web novel or the author’s primary publication) is the core canon. Adaptations like the webtoon/manhwa, side chapters, and promotional one-shots can be faithful or divergent; some of their scenes are author-approved canon while others are adaptation-only extras that enhance the experience but don’t change the main continuity.

From my experience following similar titles, there are a few practical signs to help you decide whether a chapter or scene is canon. First, check the source: if a chapter is part of the original serialized novel posted on the author’s official platform (and later compiled into official volumes), treat it as canonical. Second, look for publisher/author notes—many authors explicitly label extra scenes as 'side story,' 'bonus,' or 'omake' and will note if something is non-canonical. Third, compare endings and character arcs: if the webtoon diverges in major plot beats or introduces new character backgrounds that don’t appear in the novel, those additions are usually adaptation liberties, unless the author later integrates them into the original text. I learned to do this by bookmarking the author’s posts and cross-referencing the compiled volumes; it saved me from getting emotionally invested in a scene that only exists in the illustrated version.

Another practical tip: keep an eye on official releases and translation notes. Official translated volumes or publisher pages often say things like 'based on' or list whether content is adapted directly from the web novel episode numbers. Social media posts by the author or publisher are gold; they’ll tell you if a popular panel in the webtoon was an original suggestion from the artist or an actual scene from the novel. In fandom spaces, people sometimes call adaptation-only scenes 'fanservice' even when they're official—what they mean is that those moments enhance the adaptation visually but weren’t necessary to the canonical plot.

Personally, I treat the original web novel or the author-compiled volumes as the spine of the story and enjoy the webtoon as a delicious, sometimes divergent, garnish. When adaptation-only scenes are well-written, I let them live in my headcanon as mood and flavor, but when I’m asked about what 'actually happened' in the universe, I default to the author’s primary text. For 'A Secret Marriage... That He Won't Stop Talking About', that means the serialized novel is the baseline canon, while the manhwa/webtoon extras are best enjoyed as complementary—great for extra feels and visuals, not always essential to the official timeline. Either way, I love swapping notes about which scenes made me cry first; this one’s got plenty of moments that stick with you.
