I saw their performances for Antifragile, and you can see on their faces that they like performing. It's really great to see their energy on stage, I don't know how to describe it, but their expressions, stage presence are awesome.
I am a casual listener because of IZ*ONE so I don't know their dynamics as a group, but they do show they have a lot of chemistry; what a great way to comeback, I'm really happy to see them having success.
