Lately I've been wandering through romance threads and webcomic listings, and 'Is He Cheated Now I'm Taking My Revenge on Our Wedding Day' is one of those titles that blurs the line between a serialized novel and a comic adaptation. From what I've seen, most people encounter it as a serialized romance on webcomic platforms — it has panels, artwork, and chapter-by-chapter releases that look and feel like a manhwa/webtoon. That visual format is what makes many readers call it a 'comic' first, but it's not unusual for stories like this to originate as a prose web novel before getting the illustrated treatment.
There are also fan translations and retitled versions floating around, so you'll sometimes find it referenced as a novel in forums where readers focus on plot summaries rather than visuals. If you see text-only chapters labeled as 'chapter 1, chapter 2' without panels, that's probably a novel translation. If you're looking to confirm which version you have, check whether the release is made of illustrated pages or straight text — that'll tell you whether it's the comic adaptation or the original prose.
Personally, I enjoy both formats for different reasons: the novel digs deeper into inner monologues and pacing, while the illustrated chapters nail the dramatic wedding-day revenge scenes with expression and timing. Whichever route you find it on, it's a juicy campy-romance ride that hooked me for a lazy afternoon.
