On March 18, 2025, Kbizoom revealed intriguing developments surrounding Park Seo-joon and Kim Soo-hyun in the context of a past interview. Kim Se-ui, the host of the Garosero YouTube channel, revisited an interview from October 2024 where Park Seo-joon shared that Kim Soo-hyun played a crucial role in helping him secure his first agency, KEYEAST.
Despite this professional support, Kim Se-ui expressed a curious observation: the apparent distance between the two actors. This point arose following Park Seo-joon’s Instagram post on March 17, 2025, during his trip to Paris for business. In the post, he shared a captivating image of the city, captioned:
“What were you doing in Paris? horizontal”
Garosero highlighted the humorous connection to Kim Soo-hyun’s nickname, “YouTube Kim Paris.”This reference ties back to an older context where Kim Soo-hyun had described himself and Kim Sae-ron—who was tragically involved in a high-profile controversy—as “horizontal”and “vertical,”respectively, in a letter he sent during his military service back in 2017. Garosero suggested that Park Seo-joon’s comment on his Instagram might hint at their complicated friendship amidst the latest controversy surrounding Kim Soo-hyun.
Commenting further on Park Seo-joon’s post, Kim Se-ui remarked:
“I even left a comment there. I support Park Seo-joon. Their friendship is truly weaker than a piece of paper.”
He also noted his own comment directed at Park Seo-joon, expressing solidarity:
“YouTuber Kim Paris is being exposed by Garosero Research Institute. We will work even harder to clear actress Kim Sae-ron’s name. Park Seo-joon, fighting!”
For context, Kim Soo-hyun has faced serious allegations regarding his relationship with the late actress Kim Sae-ron, which reportedly began when she was just 15 years old and he was 27. Tragically, Kim Sae-ron took her own life on February 16, 2025, with authorities discovering her body at approximately 4:55 PM KST.
An Examination of Park Seo-joon’s Connection to the Controversy Involving Kim Soo-hyun
Garosero’s allegations of a prolonged relationship between Kim Soo-hyun and Kim Sae-ron resurfaced on March 10, 2025, fueled by old photographs released by Kim Sae-ron’s family to the Garosero channel. The research institute, known for its incisive investigative journalism, claimed that the two were involved from 2015 to 2022, raising significant ethical concerns, given the actress’s age during the initial phases of their relationship.
In the wake of these serious allegations, there has been speculation regarding Park Seo-joon’s ties to Kim Hyun, suggesting that Seo-joon’s signing with KEYEAST may also implicate him in the ongoing scandal. Information about Park Seo-joon’s agency affiliations is somewhat sparse online, with sources like The Koala’s Playground indicating he transitioned to Awesome Entertainment in 2021 after leaving KEYEAST.
India Today later confirmed in January 2024 that Park Seo-joon is currently under the management of Awesome Entertainment; however, specific details about his transition between agencies remain unclear.
The Garosero channel revisited Park Seo-joon’s remarks from his interview, originally broadcast on Jung Jae-hyung’s YouTube show, Fairy Jae Hyung, in October 2024. He candidly reflected on his career trajectory, mentioning that after completing his military service, he had little to no connections in the industry.
“After I was discharged, a friend of a friend, who was close to Kim Soo-hyun at the time, made a request on my behalf. They asked if it would be possible for me to meet with the company (Kim Soo-hyun’s agency), and Kim Soo-hyun gladly arranged it.”
Park Seo-joon further recounted that upon visiting the agency, he was directly approached by the CEO, who proposed a contract almost immediately:
“I went to the agency, and surprisingly, they brought up the contract the very same day. The CEO gave me a contract form. ‘It’s a standard contract. If you’re not sure, ask a lawyer.’ the CEO said with great confidence.”
The intricate timing of allegations involving Kim Soo-hyun and his past relationship with Kim Sae-ron has unleashed a wave of backlash from the public. As a consequence, multiple brands—including PRADA, Dinto, and Homeplus—have severed their partnerships with him, further complicating his public image.
