During introductions, MC Shin Dong Yup mentioned the time that Doyoung's older brother, actor Gong Myung, has guested on 'Hello Counselor' as well! During Gong Myung's appearance, the actor became so frustrated after hearing the story of a family that he burst into tears. Doyoung said, "I captured the clip of him [crying] from the portal site and sent it to him via messenger. He was all embarrassed, and went, 'I made a variety show into a documentary...'" 

When MC Kim Young Ja saw that Doyoung didn't make fun of his older brother like normal siblings, she poked fun by saying, "If you're really close siblings, you'd talk about it like it's funny, but you must not like your brother very much?" 

Later, one family sent in the story of an older brother who is too overbearing toward his younger sister. During the story, Momoland's JooE shared, "My older brother always treated me like a younger brother. But then he changed after I debuted. He treats me like a celebrity now. He calls me and asks me for TWICE's autographs."
