During the broadcast, Jinusean shared that they were in a KakaoTalk chat room with other singers who attended 'Infinite Challenge's 'Saturday Singers'�('ToToGa')�special. Jinu then said, "In the 'Infinity Challenge' KaKao chatroom, everyone went quiet when Sean mentioned coal delivery."�

By "coal delivery," Jinusean are referring to the campaign in which participants donate and/or deliver coal to senior citizens, the disabled, and families with low incomes to help them stay warm during winter.�Sean explained, "On that day, there were around 200 messages, but now people only chat in the chat room every other day."�

Jinu then said, "[Sean]�triggered the silence. Sean constantly asked people in the chat room to deliver coal [for charity]. People would say that they were overseas and busy, and then [the chat room] would go quiet," causing the studio to laugh at the awkward situation.�
