The buzz started when a post on a Korean online forum claimed, “I heard that Jisoo and Seo Kang Joon were here, so I ran outside. Turns out they were filming - that’s a fact.

Given the nature of the post and the popularity of the stars mentioned, fans wasted no time in speculating whether Seo Kang Joon and Park Seo Joon are gearing up for either cameo appearances or possibly even support roles in Boyfriend On Demand. With the drama already confirmed to star Seo In Guk and BLACKPINK’s Jisoo, the potential addition of more A-list talent has only amplified anticipation for what was already one of the most talked-about upcoming releases of the year.
