On the 15th, JTBC's variety show 'Please Take Care of My Refrigerator since 2014' featured BLACKPINK's Jisoo and ATZ's Wooyoung and San.
During the broadcast, it was introduced that ATZ had risen to become an icon of reverse export following the release of the title track 'BAD' from their 14th mini album.
It was mentioned that interesting comments such as "Your chest is incredible," "You're like a father who builds up the family with your chest," "A pure weight class competing with just one undershirt," and "The best innerwear idol of this era" were posted on ATZ's stage video, which viewers find themselves captivated by.
San revealed that he has acquired many nicknames through his recent activities. He said, "I am an ambassador for the fashion brand 'Dolce & Gabbana,' but people call me 'Dolsu & Gabbana,'" eliciting laughter.
San added, "Many people know me as the 'Northern Grand Duke' (a cold, handsome character from a fantasy novel who seems to live in a cold region)."

When MC Kim Sung-joo said, "It is not easy to build a body like this," San replied, "Just four or five years ago, I weighed 52 kg," surprising everyone.
He explained, "I gained 14 kg. To bulk up, I forced myself to eat six meals a day and stuffed down Digestive biscuits and milk."
Subsequently, photos of San before and after his weight gain were released. Seeing his slim appearance, Ahn Jung-hwan reacted by saying, "You looked too skinny."
San explained, "My bones grew, and muscles attached to my face as well." Ahn Jung-hwan admired San's current muscular look, saying, "You look much more handsome." Chef Choi Hyun-seok remarked, "Since you gained muscle, your gaze has changed," adding, "You've developed a certain allure," describing San's captivating eyes and causing laughter.
San said, "I thought the golden age would come. Not my personal golden age, but I thought the golden age for men with good physiques would eventually arrive."
