The member who took the podium representing Seventeen was Joshua

As UNESCO Youth Goodwill Ambassadors, SEVENTEEN conveyed a message of solidarity and hope to youth around the world. SEVENTEEN attended the UNESCO x SEVENTEEN: Celebrating Youth, Creativity and Well-Being Together event, held at the Main Hall of UNESCO Headquarters in Paris, France, at 5 p.m. on the 25th.
It was Joshua, the member who took the podium representing Seventeen. I couldn't see the speech in person, but just looking at the photos made me so proud and overwhelmed.
