BLACKPINK Concert Attendance Fuels Unconfirmed Jisoo and Seo Kang-joon Dating Rumors

Online communities in Korea are currently buzzing with unconfirmed dating rumors involving BLACKPINK's Jisoo and actor Seo Kang-joon. This speculation gained traction from various alleged 'evidence' circulating on social media, including Seo Kang-joon's reported attendance at a BLACKPINK concert.

The rumors originated from overseas SNS posts around September 2026, comparing public photos and schedules of the two stars. Key points cited by fans as 'evidence' include similar Instagram profile photos, alleged shared time in New York, similar ring designs, and the claim that Seo Kang-joon attended a BLACKPINK concert. It is also noted that Jisoo and Seo Kang-joon previously worked together on the Netflix series 'Monthly Boyfriend,' where they played romantic interests.

Local bloggers consistently emphasize that all these points are based on online speculation and unconfirmed comparisons by users, with no official statements or photographic proof of a relationship. They highlight that while Seo Kang-joon's concert attendance is mentioned, it does not confirm a romantic motive, and similar accessories can be due to sponsorships or coincidences.
