In episode 122 of the YouTube channel 'Salty type,' released on the 8th, the sibling-like chemistry between actors Ha Jung-woo and Gong Hyo-jin drew attention. The broadcast featured Ha Jung-woo, Lee Ha-nee, Gong Hyo-jin, and Kim Dong-wook discussing various topics related to the movie 'Upstairs Neighbors.'

The cast pointed to Gong Hyo-jin as the only person who can control Ha Jung-woo. Ha Jung-woo said, "The only person who can hold Ha Jung-woo on set is Gong Hyo-jin." Gong Hyo-jin explained, "I'm not usually like that, but when I see oppa, it happens. I tend to hold oppa more than people my age or younger." Lee Ha-nee added, "The only person who dares to keep Ha Jung-woo in check is Gong Hyo-jin."

Their bickering continued during the project meetings. Gong Hyo-jin harshly criticized the script as soon as she received it, and Lee Ha-nee revealed, "If you make Gong Hyo-jin laugh, everyone laughs. Ha Jung-woo's ad-libs aren't very funny." Gong Hyo-jin declared, "They're no fun. Dad jokes," causing laughter.

Ha Jung-woo shared a phone conversation with Gong Hyo-jin, saying, "She was very critical of the scenario. We talked for an hour and 20 minutes about it. I wished it would end." He claimed, "Gong Hyo-jin points out everything strange from one to a thousand. After the movie, I had appendicitis surgery. 80% of it is because of Gong Hyo-jin."

In response, Gong Hyo-jin fired back, "Oppa gave me a glare." Ha Jung-woo explained, "There were 40 guests on set. During rehearsal, Gong Hyo-jin was in front of the monitor asking, 'How are we going to shoot this scene tomorrow?' It was the first time in my life I experienced buffering." Kim Dong-wook added with laughter, "I've known Ha Jung-woo for 18 years, but it's the first time I've seen him cry."

Ha Jung-woo appealed, "Everyone was there, and I got kept in check. It was enough to cause appendicitis," while Gong Hyo-jin responded, "I don't remember that at all." Eventually, Ha Jung-woo surrendered, saying, "I can't win against Gong Hyo-jin."

Toward the end of the broadcast, a gaslighting debate broke out. Ha Jung-woo complained, "Gong Hyo-jin says, 'There are rumors these days,' then that night she asks who spread those rumors. She keeps gaslighting me. You can't do that, Gong-bly." Gong Hyo-jin calmly replied, "I'm just warning you."

Watching the two, Lee Ha-nee summarized, "They are Ha Jung-woo's favorite actors whom he acknowledges. They give each other unconditional love." Ha Jung-woo and Gong Hyo-jin revealed, "Even though we seem to have a bad relationship, we're actually the closest," and "Ten years ago, we promised that if we weren't married by 60, we'd live together," causing laughter.

Despite their bickering, the deep trust and chemistry between Ha Jung-woo and Gong Hyo-jin brought great laughter to viewers. Through affectionate jokes and sincere conversations, they provided enjoyment to the audience.
