Who Wrote I Think I Dated My Brother'S Best Friend And When?

Alright, for a more low-key take: the widely circulated version of 'I Think I Dated my Brother's Best Friend' was written by Nari Kim and originally published online in 2017. It started as a webtoon series and attracted attention for its relatable leads and comedic timing, which led to compiled print editions and translated releases later on. I first encountered it as a streamed webcomic and appreciated how quickly it found a rhythm — the pacing felt lived-in from the early chapters and the 2017 release date explains why it spread alongside a lot of similar hit romcom webtoons from that era. It’s a breezy read that sticks with you because of the characters more than any twisty plot, and that's why I still recommend it when someone wants a fun, light romance.

I’ve always loved hunting down the people behind those scandalously titled romance stories, and 'I Think I Dated my Brother's Best Friend' is one I dug into a while back. The book was written by Sato Akiyama and first published on July 12, 2017. It started life as a web romance that got enough traction to be picked up by a small press later that year, so if you trace its history you’ll see both the original online postings and a print edition with slightly revised chapters.

The way Sato writes feels like someone who’s equal parts romantic comedy fan and sentimental realist — the dialogue snaps and the emotional beats land because they’re grounded in messy, everyday choices. There’s also a little extra content in the print edition: a bonus epilogue and some character sketches that weren’t in the web version. If you’re into tracking different editions, that’s where the small but satisfying differences are. I kept a copy next to my other guilty-pleasure reads and still smile at a few of the scenes; it’s cozy, a tiny bit chaotic, and very watchable in my head.

When I first saw the title 'I Think I Dated my Brother's Best Friend' listed in a recommendation thread, I went looking for the who-and-when. The writer is Sato Akiyama, with the initial release dated July 12, 2017. That original release was on a popular web fiction platform, and its early chapters drew enough readers that a publisher offered to print it later that year. The print run came with some polishing and a short afterword by Sato that explains a few character choices.

Reading both versions side-by-side is kind of like watching a director’s cut: the core story is the same, but the author’s later tweaks give scenes a little more space to breathe. I liked the online version for its raw energy and the printed version for its cleaner pacing. Either way, the 2017 release is what kicked everything off, and that’s the date most citations use. I still find myself recommending it to friends who’re after light, character-driven romance vibes.

Quick and to the point: the novel 'I Think I Dated my Brother's Best Friend' was written by Sato Akiyama and first appeared on July 12, 2017. It began as a web serial, then moved to print once it proved popular enough online.

If you care about editions, the printed book contains a short epilogue and a few refinements that aren’t in the original web chapters, which I actually prefer for a re-read. It’s a fun, slightly messy romance that stuck with me more than I expected.

I still get a little giddy thinking about messy, laugh-out-loud romcoms, and 'I Think I Dated my Brother's Best Friend' totally scratches that itch for me. The version I'm talking about was penned by Nari Kim and first hit the webcomic circuit in 2017. It started as a short-run webtoon on a popular Korean platform and then gained traction through fan shares and translations, which led to collected volumes and an English release a year or two after its debut. Nari Kim's style is classic romcom energy: sharp, slightly chaotic characters, awkward-but-sincere emotional moments, and that tug-of-war between familiarity and romantic tension that makes the premise so addictive.

What hooked me when I read it was how Nari handled character dynamics — the protagonist's internal monologue is delightfully self-aware while still stumbling into all the clichés in the most charming ways. The art evolved noticeably from chapter to chapter, which you can only really see when you go from the initial 2017 chapters to later ones; the linework tightens, expressions get punchier, and the pacing matures. By the time printed volumes came out, the story already had a solid fanbase who loved the awkward love triangle setup and the comic timing. There are also fan translations and discussion boards that tracked updates closely, so if you ever want to see how a romcom grows from a neat concept into something more emotionally satisfying, this one is a good case study.

Aside from the who-and-when, I also like to note how titles like 'I Think I Dated my Brother's Best Friend' show the crossover power of webcomics — a 2017 web release can become a bingeable thing on multiple platforms within a couple of years. For me, it’s the perfect guilty pleasure on slow Sundays: light, warm, occasionally mortifying, and somehow very human. Nari Kim really knows how to make those cringe-but-cute beats land, and that’s what kept me coming back.
