Signing event for the 13-hour silent retreat to fulfill the 'Manager Kim' viewership rating pledge ~

At the press conference for 'Manager Kim,' he stated, "Over 10% viewership would be a huge hit, but since So Ji-sub is returning to SBS after 13 years, I will aim for 13%." Joo Sang-wook, who was also present, suggested, "How about observing a vow of silence if we reach 13%?" to which Yoon Kyung-ho promised, "Then I will observe a vow of silence for 13 hours." It is reported that he plans to begin his 13-hour silent observance and film related content after appearing on the live broadcast of 'Cultwo Show.'
