It all started when another guest on the show, singer Lee Sejoon from the ballad duo Yurisangja serenaded the cast and audience with a special performance.

Host Kim Yong Man then noticed that Tsuki started crying.

The rest of the cast members and guests asked Tsuki about the reason behind her sudden tears.

The lyrics are a bit hard for me to understand, but… I’m so honored to be able to hear the song live like this. I’m so [happy].

The song that Lee Sejoon sang, titled “I Love You”, is actually a well-known 1983 Japanese pop ballad by singer Ozaki Yutaka.
