WINNER's Song Min Ho revealed he wouldn't introduce his younger sister to his longtime friend P.O.

On the April 4th episode of 'Knowing Brothers', 11-year friends Song Min Ho and P.O. as well as 14-year Wooyoung and Jo Kwon featured as guests. When the 'Knowing Brothers' asked if they would introduce each other to their younger sisters, Song Min Ho hesitated, saying, "That's... I've been really happy these days, and the thought of that brings me down." P.O added, "If they want to date, then they can. I don't have a younger sister though. I'm an only child."

Wooyoung also said of Jo Kwon, "I think I'd introduce them. Jo Kwon's really kind and humble," while Jo Kwon said, "I don't think I'd introduce him to my younger sister. Of course, he's kind, very sincere, and very good to the people around him, but he's too popular."
