On January 10 KST, singer Sung Si Kyung uploaded a video on his YouTube channel, featuring an entertaining visit from Kyuhyun.

During their chat, Kyuhyun humorously revealed, “Is anything different with me? I lost weight. I lost about 6kg,” to which Sung Si Kyung jokingly responded, “Is anything different with me? I gained weight,” eliciting laughter from both.

Kyuhyun then delved into a hilarious incident involving a missed flight with Sung Si Kyung during a drinking session. He recounted, "It happened during a nationwide tour in Japan. There was only one flight departing from Korea at 9 a.m. each day. I told Sung Si Kyung, 'The flight is at 9 a.m. tomorrow, so I have to leave at 6 a.m.' Sung Si Kyung replied, 'Oh then you can leave at 5:30.' I thought to myself, 'I haven't even packed, maybe I should just go?' But Sung Si Kyung convinced me and said, 'No, you can leave at 5:30 and pack then,'" Kyuhyun mimicked his friend, evoking laughter from the audience.

Ultimately, Kyuhyun ended up drinking until 5:30 a.m. He continued, "I remember waving to Sung Si Kyung in the taxi, saying, 'I'm leaving, bro.' However, the next thing I recall is waking up half-naked on the bed, wearing only jeans, and it was 11 o'clock in the morning."

Curious, Sung Si Kyung asked, “Where was your manager?” Kyuhyun explained, “There was no one there. I wasn't even wearing underwear, just half-dressed in jeans. I asked myself, 'What's going on here?' and decided to call my manager." Kyuhyun went on to explain that the manager had initially tried to wake him up at 6 a.m., only to find him sleeping naked. Unable to get him dressed and to the airport, the manager eventually had to make the call, “I don’t think Kyuhyun can make it today.” 

"Who told you to drink that much?" Sung Si Kyung said to Kyuhyun, as Kyuhyun mischievously indicated that it was Sung Si Kyung himself. Sung Si Kyung said in response to defend himself, "Listen, you can lead a horse to water, but you can't make it drink," as the two laughed together.

Fortunately, the mishap didn't result in a missed performance, as it was scheduled for the day after.
