There's a fresh and young atmosphere which is wonderful <3 It's the first time in a while that members blogged so much with them being backstage and stuff..
Probably the first time in a while they've actually been backstage all of them and had time and stuff. The winter concert and spring concert ofc, but I imagine those are way more stressful and such than waiting for your turn to go up and take a close up shot is.
Green screen doesn't mean it's awful. It used to a few years ago but things have changed since then. Chikyuu and Kare to issho for example were both green screen festivals and everyone seems to love both of those.
