Lee Jin-ho also explained that as for the 2018 video released by the YouTube channel "Horizontal and Vertical Research Institute", in which Kim Soo-hyun went to Kim Sae-ron's house for supper while on vacation, it was purely because Kim Soo-hyun got along well with Kim Sae-ron's family at the time and had a personal relationship, so he visited as a "friend". Lee Jin-ho emphasized that "Kim Soo-hyun only went there that once."

In addition, Lee Jin-ho also exposed a video of Kim Sae-ron kissing another man on the street in May 2019, which lasted nearly 5 seconds.
