This type of production in my ratings are 6/10, it is higher simply because I love everglow, they are my ultimate k-pop group (or even in general) but even because of that I could not give higher rate than 7 - it would just not be fair.
But this was really fun watch, makes you know girls a little better and it is always nice to see your favourite idols a little more.
If you consider watching - watch it, Everglow is group full of amazing and talented idols, maybe this make you check their music out - so definitely worth giving a chance.
