On 7.02.2019 Wonder Girls Yubin and Hyelim were broadcasting on Vlive.

Amongst other things that they were talking and answering questions, they were also talking about JYP new girl group ITZY.

Yubin said that she saw ITZY many times when they were practicing and that they are very hard working girls and very bright. They give teen power feeling.

Hyelim asked Yubin if she has talked with them and Yubin said that she hasn't talked much with them but she cheered them with phrase 화이팅!

Yubin said that when ITZY was practicing and when she came, they immediately greeted her.
She also said that they have great manners and that she likes them.
