It was revealed that Ju Ji-hoon mentioned his ex-girlfriend during a drinking session when he appeared on the YouTube channel 'Sung Si-kyung' along with Kim Hee-chul in the past.

In the broadcast, Kim Hee-chul asked Ju Ji-hoon, "If you like someone, aren't you the type to go all out?" Ju Ji-hoon replied, "I'm the type to observe." While drinking, Ju Ji-hoon said, "Am I a bit drunk? I've thought about it for a long time, but since you (Kim Hee-chul) talk a lot, I keep looking at you. My heart aches because you look so much like my ex-girlfriend." To this, Sung Si-kyung responded, "You must look a lot alike." Kim Hee-chul joked, "Is your ex-girlfriend Kim Byung-ok hyung?" and even did an impression of Kim Byung-ok's voice.

Meanwhile, Disney+'s 'Climax,' starring Ju Ji-hoon and Ha Ji-won, ranked number one domestically and reached number one in Indonesia and Thailand within its first week of release.
