Did Kim Soo Hyun really tell the truth about his relationship with the late Kim Sae Ron? A new leak suggests otherwise.
On March 14, YouTube channel Garo Sero Institute (Gaseyeon) dropped a bombshell by revealing a KakaoTalk screenshot where Kim Sae Ron allegedly wrote, “Our relationship lasted from November 19, 2015, to July 7, 2021.” The channel explained, “Kim Sae Ron kept a diary, so she recorded the exact dates.”
Adding to the controversy, a newly surfaced photo shows Kim Soo Hyun wearing a “JDC” hat while posing closely with Kim Sae Ron, who was in a red hoodie.

Initially, Gaseyeon speculated that the picture was taken in Jeju due to the hat’s marking, but they later claimed, “After checking details, we confirmed it was actually taken in front of Kim Soo Hyun’s residence at Galleria Foret.”
Online users quickly dug deeper, pointing out that Kim Soo Hyun was often seen wearing that exact JDC hat between 2015 and 2017. Some even uploaded comparison photos from those years as proof.
One netizen, claiming to be an employee from the brand that produced the hat, added even more fuel to the fire, stating:

“That hat was part of the 2016 Spring/Summer collection. It was sent as a sponsorship in the winter of 2015. Kim Soo Hyun was seen wearing it in airport photos from December 2015. If he continued wearing it by choice, there should be sightings beyond 2016, but there aren’t any.”
They further claimed that in 2017, the brand provided a new black-lettered version, which Kim Soo Hyun also wore for only a short period.
Earlier that day, Kim Soo Hyun’s agency, Gold Medalist, released an official statement:

“Kim Soo Hyun and Kim Sae Ron dated from the summer of 2019 to the fall of 2020, after Kim Sae Ron became an adult. The claim that they were in a relationship when she was a minor is false.”
The agency also addressed the military letter controversy, explaining that Kim Soo Hyun sent letters to many close acquaintances, and his phrase “I miss you” was meant casually.
Despite Kim Soo Hyun’s denial, netizens are now questioning his credibility as more evidence keeps surfacing.
Initially, the actor completely denied dating Kim Sae Ron, calling the rumors “groundless.” But after intimate photos, including a kissing picture, were exposed, he was forced to admit the relationship. Now, many are wondering—is he just trying to cover up the timeline?
With the latest claims involving Kim Sae Ron’s diary entries and the hat’s sponsorship history, more contradictions are emerging. If his denials continue to be debunked, he might end up labeled as “the boy who cried wolf.”
Meanwhile, Gaseyeon initially planned to reveal high-exposure photos of Kim Soo Hyun, including one where he was allegedly washing dishes at Kim Sae Ron’s house without pants. However, they announced just before their live broadcast:
“Kim Sae Ron’s mother expressed concerns about Kim Soo Hyun’s mental state after today’s statement. She worried that he might make an extreme decision.”
Due to the bereaved family’s request, Gaseyeon ultimately chose not to release the photos—for now.
