"We’ve been on stage before in the United States, but it was our first time where the whole concert was dedicated to us and it was a big moment. We were overwhelmed, felt great, and we're very grateful at the end of the day," said Dahyun. "We wanted to communicate better with the fans, so we had prepared some English phrases and expressions, but we were so nervous that we were not sure if we did an adequate job; we’ll prepare even better next time."
She continued: "Tours always leave us some regrets and thoughts that we could have done better and should have done better. We always attempt to change the choreography, the set list, and we’ve learned! It is indeed a learning process and for the next tour we’ll visit even more regions and connect with more ONCE in different parts of the world."
Leader Jihyo added: "Looking back on the road we’ve traveled, we are so grateful for the love and support we received. During our debut, it was our dream to hold just a single concert and now we are immensely proud to complete even a world tour. And on top of that, making this YouTube documentary now, it feels like 2019 has been a big turning point for us."
