Suji Kim

Suji Kim is the South Korean fantasy-romance writer who turned Under the Oak Tree into one of the clearest examples of Korean platform fiction scaling into global publishing IP. Ridi gave the series its first breakout runway in Korea, and Penguin Random House now markets Kim as a New York Times bestselling author whose webnovel success converted cleanly into international print demand.

That matters because Kim is not being framed as a one-book anomaly. Penguin Random House also lists Twilight Poem and There Is a Mouse in My House in her published slate, while the wider adaptation economy keeps proving that her lane travels well beyond prose. HITKULTR has already tracked how Kakao Entertainment, Kakao Page, and Kakao Webtoon tapped that same market appetite around The Forgotten Meadows.

Kim matters because she sits where romance web fiction stops looking niche and starts behaving like durable entertainment infrastructure. Under the Oak Tree has already moved from digital serialization into award-winning platform success, webcomic acclaim, and global print. The larger point is not just that one title got big. It is that Suji Kim now reads like a repeatable premium-IP name inside the Korean story business.
