K-Pop debuts can be tricky things. At times, they’re the best song a group delivers. Sometimes, they’re the only song a group delivers!
But, debuts can also be huge wtf moments in an artist’s career. In this feature, I’ll be looking back at debut songs through the prism of time, re-evaluating how well they hold up and how representative they are of an artist’s eventual singles run.
Debut Date: June 28, 2016
Review:
This re-evaluation has been a long time coming, and I must move between several different states of mind to write it. First, we head back to the early summer of 2016. Given my intense desire for a sweet, hyper-melodic girl group sound to return in 2026, it’s hard to believe there was ever a time I was sick of hearing it. However, early 2016 had been flush with the style… so much that my initial review of Gugudan’s Wonderland was unfairly harsh on the song. I guess I simply hungered to hear something else, never anticipating what that “something else” might be and the hold it would go on to have on K-pop over the next decade.
Of all the reviews I’ve written, Wonderland sticks in my craw in the same way that the review for WJSN’s excellent Secret does. Going back to listen to this, I can’t understand what I had such a problem with! If Wonderland was released this year, I’d be raving about its refreshing energy and sung (sung!!) melodies. Sure, it’s sugary sweet to a fault, but the overall sound is buoyant and exciting in a way we rarely hear anymore. The chorus is layered with harmony and represents an actual climax in the song rather than a dull beat drop.
Even so, I’m not going to go crazy with my updated rating. Within the realm of these sweet, melodic girl group tracks, I still think Wonderland is second tier. However, being second tier within a genre I happen to love still warrants a high score. Its production misses the chance to become truly iconic by bending to too many tropes, but the song as a whole has such satisfying heft and payoff. It truly brings a smile to my face.
Does the song hold up?
Yes! Far more than I would have thought at the time.
Is the song stronger or weaker than most of the artist’s title tracks?
They had one or two stronger title tracks (I was too harsh on their discography at the time), but this is definitely in the upper half.
Does the song represent the artist’s music going forward?
It feels a bit sweeter than most of their music.

What a difference a decade makes. I think it is too sugar sweet aegyo for me, but I would still give it maybe a flat 8 because it is well done happy joy fun, and we need more happy joy fun in the world right now.

even the general sentiment at the time of release was pretty meh, from what I remember. I wasn’t too crazy about it either back then but in retrospect, this was an amazing debut (the iconic “whistle”/falsetto adlib in the final chorus!) and I’d gladly take 20 of these today 😭
if you should do another one of these soon, I’d love either Double Up by Two X or We Are A Bit Different by EvoL (unfortunately both forgotten girl groups today)

I think the burying of Sejeong, plus the styling caused a lot of people to unfairly judge this song.
LikeLike
yes!! i actually vividly remember this – i think the big issue for a lot of people was that they felt like they didn’t get the concept they were promised. iirc jellyfish advertised it as mystical/magical concept and everyone was expecting something like closer – oh my girl. being a cute concept enjoyer at the tail end of 3rd gen was torture lol, the hate these groups would get was ridiculous

Man, I recall so many people at the time would go absolutely bananas for anything “girl crush” or with an EDM drop, and if any group dared to shift their concept to something “cuter” or to a lighter, more innocent tone there would be waves of international fans complaining and dropping the group like a rock (eg CLC going from Hobgoblin to Where Are You and girl crush fans flipping their lids over it) or screaming that their company was mismanaging them just because they weren’t Blackpink clone #3967. I liked both styles of music, but I enjoyed the melodic stuff way more and I could see even back then that it was starting to fade away in kpop songwriter’s priorities….and now we’re here in 2026 in a barren wasteland of melody lol. Didn’t know what we had.

we all have times of our lives where certain songs sound like a 10, and other times sound terrible.
sometimes a gem is only a gem because it’s the stone among stones that reflected light in just the right angle and time

wait, nick, you mentioned secret by WJSN in this review and called it excellent, but you only rated it a 7.5?

He has mentioned a few times how the song was underrated during release and now loves it… much like Wonderland, therefore referencing Secret as the underrated poster child here.

Wow, glad you posted this! I totally remember hating this when it came out, and though I’m still iffy on the verses, the chorus is such a bop!
It’s such a shame that so many of the post-IOI groups were fumbled. I know there were multiple factors going into that, but rewatching this video reminded of how many girls they tried to shove into all these groups, and with such a massive gap in recognition!

i miss them so much! their discography was severely underrated as well as their talents – sejeong, haebin, soyee, and nayoung made a great vocal line and i remember loving their dance practices. it sucks we didn’t get more music, a girl like me and wonderland were such standouts

The Boots was peak actually. That song and MV combo and the whistle hook in it are still some of the first things that pop into my head when I think of 2018 kpop.

I loved this song when it came out and I still love it today and have it in my regular rotation haha. I’m glad to see there’s some more love for it on here now, and I really think Gugudan had a discography that, while not as good as their labelmate, is still really solid.
