During the livestream on March 17, the host of YouTube channel Garosero dragged Park Seo Joon into Kim Soo Hyun's scandal with Kim Sae Ron, when he suddenly mentioned a post on the actor's Instagram.
In the post, Park Seo Joon posted a photo with the content: "What did I do in Paris? Garo".
Garosero analyzed: "This story is not very noteworthy. Kim Soo Hyun's nickname is "YouTuber Kim Paris". He exchanged love letters expressing his love for Seronero (Kim Sae Ron's nickname that the late actor's family confirmed that he was given by Kim Soo Hyun).
Then Park Seo Joon posted a status like that again, it reminded people of the Garosero Institute. I left a comment on Park Seo Joon's account. I said I support Park Seo Joon".
In addition, the host also affirmed that the friendship between Kim Soo Hyun and Park Seo Joon is only as fragile as a piece of paper, lighter than feathers.
However, Park Seo Joon's fans have expressed their dissatisfaction with the move, saying that the Garosero channel is deliberately improvising, causing Park Seo Joon to be misunderstood as having a connection to Kim Soo Hyun's scandal.
They explained that garo means terrestory and Park Seo Joon wrote it because he posted a photo taken in Paris in a sideways manner, completely without any other meaning.
