On the evening of March 18, YouTube channel Garosero posted a video that was said to have been filmed by Kim Soo Hyun himself at Kim Sae Ron's private home. The video was provided by the late actor's family, affirming that this was evidence of the two dating at Kim Sae Ron's house.
In the video, the man, believed to be Kim Soo Hyun, who did not show his face, used his hand to massage Kim Sae Ron's back when she was constantly stabbed. Kim Sae Ron smiled brightly while watching TV.
Garosero sent a message to Kim Soo Hyun: "We hope you will make an official announcement tomorrow. If you say that the person in the video is not you, we will post a clear video of your face.
However, Garosero channel does not specify when the video was filmed.

After the video went viral, netizens found some signs that could prove the video recording time.
The audience noticed that Jennie's (Blackpink) song "Solo" resounded at the end of the video, which Jennie released the song on November 12, 2018, so the video was definitely filmed after this time frame.
Another comment said that in the video, Kim Sae Ron was watching Knowing Brothers episode 251 aired in 2020, because the voices of artists Shindong, Heechul (Super Junior) and comedian Soo Geun appeared.
Other comments speculate that the video was filmed after 2019, because Kim Sae Ron was given a private house by the company when he joined in 2019.
Previously, Garosero channel and Kim Sae Ron's family resolutely accused Kim Soo Hyun of dating the late actor when she was a teenager, from 2015 to 2021.
However, Gold Medalist stated, Kim Soo Hyun and Kim Sae Ron dated from the summer of 2019 to the fall of 2020, after Kim Sae Ron was old enough.
Many viewers asked Kim Sae Ron's family to provide clearer evidence to prove that Kim Sae Ron dated Kim Soo Hyun when she was only 15-16 years old.
On the other hand, Garosero is being opposed by a part of the audience, saying that this YouTube channel intentionally took advantage of the noise to "interact".
The illustrative image used by Garosero for the livestream on the afternoon of March 18 was criticized for being sensitive, disrespectful to the deceased and violating their private lives.
