I would say Not shy was a good break through for itzy. People have been wanting a change in concept that isn't just confidence, so not shy had a change. It showed being confident in LIKING someone so it had a twist of the concept. The music video was perfection, the fashion was truly immaculate even if it was loud and colorful. It fits itzy. The album was pretty good, not shy is a catchy summer love song with confidence which is what kpop needs. The desert theme and colors fit so well for itzy and worked so well with everything. I would say Be in love and SURF are very good songs with nice vocals. The album is focusing more on vocals which I love to see. Itzy has not shown their true vocals yet so it's good to see them changing it up a bit this era. I would rate this era a 9/10, the only problem is that the album isn't as show stopping as It'z me but it's still a bop none the less. It still needs to grow on me but this era is deserving of 5 stars. I'm glad for not shy they focused more on live vocals than the very energetic dancing. They delivered a WONDERFUL performance with good fashion, dancing, and LIVE vocals.
This album/era is a good 9/10.
