I agree, especially with what people are saying about Nayeon.
For me personally, this title track is one of my faves from them. I'm not much into their music, but I really like the members and watch alot of their content etc. I know what they are capable of (especailly when they perform cover songs at concerts etc) so the overproduction of some parts in terms of their vocals is noticeable.
It's not the first time Twice vocals are overproduced obviously, but it would be nice if JYP allowed for a more natural tone. I'm sure Twice would surprise alot of people if that was the case.
Perhaps if this really is the "turning point" as Chaeyoung suggested, Twice could really capture my attention in terms of music. I hope they do!
Overall though, this is my fave comeback from Twice! Fun MV and generally a good song!
