About Rowoon & Inseong
The fan-shipped pairing between SF9's Kim Seokwoo (Rowoon) and Kim Inseong is rooted in their years as groupmates in SF9, which debuted under FNC Entertainment in October 2016. Both are vocalists, and Rowoon in particular became one of SF9's most prominent public-facing members due to his acting career alongside his idol activities. A widely noted moment between Rowoon and Inseong occurred during SF9's Summer Breeze comeback stage on SBS Inkigayo in July 2020: Rowoon's 192cm height inadvertently blocked Inseong (184cm) from the camera frame. Once Rowoon realized, he immediately bent down to ensure Inseong could be seen — a considerate, low-key gesture that fans circulated as an example of his attentiveness to groupmates. After Rowoon formally departed SF9 in September 2023 to focus on acting, group reunion moments became more notable. At FNC KINGDOM Japan in December 2023, Rowoon and Inseong performed together on stage for the song 사랑한다는 말 (Say I Love You), giving fans a celebrated reunion moment. Their bond is presented by fans as a warm senior-member friendship built during their shared SF9 years.
This is a lower-profile ship within the broader K-pop fandom, primarily followed by Fantasy (SF9's fanbase). Content is conservative — based on groupmate interactions and reunion moments rather than an active, heavily documented friendship dynamic. The ship does not have a widely used portmanteau.
