this album shows twice's maturity in their music. The development and growth from Twicetagram back in 2017 till now display immaculate maturity. Every single songs on here don't just stick to the umbrella term, retro at all. They are still retro, but with different vibes, like newtro, r&b, soul, edm, ballad.. Twice is probably the one of the most diverse girl groups ever after RV. Well, what can I say, this should be album of the year
