HaHa, who is currently in self-quarantine after coming in contact with a positive case of COVID-19, gave an update on how he is doing on the KBS Cool FM radio program 'Park Myung Soo's Radio Show'.

On December 15, HaHa was connected through a phone call on the radio program 'Park Myung Soo's Radio Show', where he stated, "My fingernails disappeared because I'm so anxious. I'm worried about my children. [This is making me] go crazy." On this day, HaHa had originally been scheduled to appear on the radio program, but cancelled his schedules due to his self-quarantine. HaHa added, "I slept in my studio room because I couldn't go home. I did like it. [My wife] Byul was very angry. She's sensitive. [It's because] she feels really bad for me."

It was previously reported that HaHa had canceled his appearances in two originally planned schedules in order to undergo a COVID-19 test, after Yoo Jae Suk tested positive.
