하루종일 애프터스쿨 봤더니 이게 다 뜸ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ아니 이런 것도 했었냐고 다들 열심히 살았다 증말

nana has the type of beauty that makes everyone else in the room uncomfortable

Two big girl groups performing their biggest hit songs. It's just too tough for me to call a winner.

nana.... i don't know..... she's Just perfect.... XD

Now... can someone tell me why on Earth is After School so underrated?! Any logic explanation? ;___; This performance was madly NEAT.

It's sad that people only know victoria for her flexibility and think that she can't really dance when she has been learning ballet and traditional chinese dance for years in one of the best dance academies out there. It's also sad that people think she can't sing just because she doesn't get any real singing lines in f(x) songs (not saying that she's the best vocalist or anything) because there are better vocalists. It's sad that any little success f(x) gets is all undermined and said to be because of sm when jessica jung promotes and supports f(x) more than sm does and when sm treats them like stepchildren. It's sad that people automatically equate pole dancing with sluts and prostitution when it also happens to be a piece of art and an an actual dance that requires incredible coordination and is probably one of the hardest dances there are. It's sad that people bash idols for sexy concepts and dances without thinking about why it's done in the first place.

People are always underestimating After School, I wonder why... They are still one of the most well known girl groups to the general public of South Korea, they still chart within the top 10 whenever they comeback, and they have a bigger fanbase INTERNATIONALLY comepared to their South Korean fanbase. They are know for their dancing skills, nobody can deny that. They were and always will be known as the best dance girl group. Sure they don't have the strongest vocals, but vocals aren't everything. There still is presentation, and After School never dissapoints with the strength and charisma hat they bring on stage. And for those who don't know, After School would belong in the same tier of girl groups like Secret, Miss A, 4minute, so they are very well known.

i love f(x) and after school but damn after school's performance gave me chills, they know how to run the stage

아 애들 다 풋풋한거봐 함수니들이랑 앺스 둘다 열심히 살았다

f(x) is such a unique girl group. they are not like the others that has to do sexy concepts just to make them popular. Of course there may have some similarities in their every comeback, because it's not them who decides about their concept or anything, we can say that they are totally under their agency's control, that's why even if fans want them to do something new or anything, they can't. But the real thing is that f(x) is really really a UNIQUE group. SM needs to promote them more.

after school could do electric shock but fx couldn't do flashback. i loved both groups since 2012 but after school is supreme

에펙은 라이브 진짜 많이 진짜 잘했구나. 연말무대에 라이브는 대단한데

fx's visual is no joke. Each member is beautiful in their own way～i like them the best coz they are so comfortable to look at😍

Even in 2022 I don't know any girl group that can come close to After School. I love both groups and I'm kind of SM stan but After School is top tier for me. I ve been a kpop fan since first gen but After School performances has always been the best.

I hate how eerily quiet the crowd is at AS' performance.. I mean like srsly AS slays every stage they're in yet they are highly unappreciated.... smh

The best thumbnail MBC ever made.

please After School comeback

원래 이게 아이돌이지.... 이때 아이돌들은 라이브 그냥 다 씹어먹었었는데... 이래도 라이브 못한다고 욕먹었는데...

아직 여기로 넘어온 사람은 별로 없군ㅋㅋㅋㅋㅋ

Flashback sounds like a hot club version here, really like it. And omg Nana... I think I have to break up with my boyfriend :D she's so damn hot!

I can't stop replaying 4:51...After School is just so effortlessly captivating.

4:53 is the best shot. Nana looks fantastic!

After School blows fx out of the water based on that stage presence and vocal skill. It's such a shame that they can't get more popular due to lack of company funding...

Not even beong biased After School Slay

Definitely AFTER SCHOOL beyond beautiful! The most gorgeous girl group in the KPop history 💗💗💗💗💗💗💗💗💗

설리와 이가은이 같이 나오는 무대네...둘 다 잘 풀렸으면 너무 좋았을건데...설리는 너무 심적으로 힘들어했고ㅜㅜ가은이는 조작으로 14위되고ㅜㅜ...연예계는 정말 싫네

i love how f(x) are singing fully live~

OMG!!!!At 2:25 they were holding a banner saying 'KhunTorian'

I don't know what's u guys said... But the point is.... U can see how gg back then always perform live (singing live) u can clearly hear that without any doubt. But gg nowadays regularly use loud backtrack n that's why people nowadays tend to watch mr removed to make sure they sing live or not. And some of fandom just backup their fav with hard choreography as an excuse. Hahahh funny how back then girl group also have hard choreography but still singing live. Nowadays gg just focus more on performing perfect dance rather than vocal.

3:20 That is probably one of the most single coolest dance moves I've ever seen in my 14 years of life on this planet.

I'll go with After School!

I like f(x), their unique style of swaying away from the typical sexy appeal that most girl groups go far is something I like about them!

This is my most favorite FLASH BACK stage. Music & choreo arrangements and their outfits are pretty good, and also image quality is good!

I can feel the stress the girls are feeling. debuted 4 years ago and still has little attention from SM. they need attention and at the same time rest. Only some fans can see their uniqueness which I'm sad about because f(x) is truly unique. I hope their training for 4 years wouldn't go to waste just because of little attention PS. please excuse my wrong grammars. English isn't my first language

with this 4:51 in their choreo while promoting the song, I'm sure it would have made the song ever more of a hit, seriously they are all mesmerizing :D

AS is a talented group in Kpop! It's a truth! they make a lot of possibilities than others.

Both groups are amazing. F(x) are amazing at performing live. And have so much talent. After School are the best dancing girl group in kpop! No one stood a chance against them in any Dance Battle.

Uee and Nana killing all Playgirlz and Boyz with their new move at 4:53!! ♡

I'm a metalhead who is just now loving kpop, and there's really no contest here .. No shame to the first group, but After School is just flat out amazing here -- Flashback is a great song and the blonde ( Nana ? ) is about as hot as a human can get

4:13 Flashback (AfterSchool)

f(x) was like, "Let's all wear blue platforms boots and not tell Sulli" lol

Doing anything versing After school is like digging your own grave. They're unbeatable!

Why is there even a competition?? f(x) and After School are both amazing artist! But this is my opinion: f(x) is definitely better at singing than After School. But the dances of After School are so much better f(x) I mean, nobody in the K-pop world has done a pole dance before! There is no competition both of these groups are amazingly talented and they all work hard! So why a competition?

The arrangement for Flashback is incredible!

AFTERSCHOOL THE BEST PERFORMANCE OF ALL K-POP

AFTER SCHOOL KILLED IT! THEY'RE THE BEST

2012: two big girl groups 2019: where are fx? where are after school? I MISS THEM :((

And this is what I love about 2nd gen groups! They f*ckin sing LIVE! Even the "Na na na na" part in Electric shock is live! 3rd gen needs to keep up. Just saying 😅✌

After School are just pure Goddesses and perfection. SLAAAAAAY!

Only 2nd Gen have this untoxic battles. Last of a kind

one of my favorite performance of Flashback

F(x) have such complicated dances, as well as unique songs and an edgy sound. They also manager to sing live!

why is jooyeon so underated she is the most beautiful member of after school

anyone else hear the random guy shouting while f(x) was preforming??? XD

f(x) the best group unique concepts!! and have a lot ot reproductions!! millons

Just love this version of Electric shock ! Amber and Luna are just great !

Anyone who says they are lip singing needs to actually listen to their voices

how do ppl find fx boring.. i do not understand... their songs are so much fun and sooo catchy they sing well and dance well do have really have to go from sexy to cute to strong to crazy or to more in order to be UNIQUE? they rock at their concept. fx has their feel im NOT saying groups who do many different concepts are not unique. they ARE also. like AS and snsd :)

F(x)'s performance was AMAZING, but I couldn't enjoy it as much because of the fact that guys were screaming in the background almost every second.. 0.o

those outfits by AS my god just kill me already

I think this is best of the best f(x) perfomance. This is what Live performance of f(x) should be. Not just the same dance choreography and the same music every performance. F(x) DAEBAKK!

Nana!! Anything with Nana is a winner

AFTER SCHOOL SAVED KPOP

I miss F(x) so much. Can someone bring these Kpop songs back like seriously? Idk what are some of those crappy Kpop songs nowadays and all these so common concepts like come on, try something new. However I'm still thankful for those groups that are releasing good songs or still releasing good song.

ชอบ Flashback ชุดนี้จังง ♥ AFTER SCHOOL FOREVER ♥

SM Stan here xD BUT AFTER SCHOOL is (for me) better

Love nana and uee's dance moves. So cool.

AS was the first girl group I loved in K-pop, but I gotta say that f(x) won this one. Their vocals are insane 😍 They have Luna who is one of, if not the best, vocalists in K-pop.

ahhh f(x) and afterschool two of my favorite girl groups i feel sad that they don't have comebacks anymore :((

I have full respect for groups who sing live and work hard. They are both great.

Luna looks amazing!! I always love it when she performs. Such a strong presence!

I honestly felt like this battle wasn't really fair......afterschool is amazing but i think lip singing is unacceptable compared to fx who actually singed live.

Afterschool. I miss them so much.. Pledis is being really unfair,, making Jung ah and jooyeon leave without any activities before. If Afterschool was busy till 2015 and 2016, Jung ah and jooyeon would've renew.. But since they need money, but pledis doesn't care about anymore they graduated. Jung ah said for one year, she wished to be on stage and stuff, but the result, graduating. If you made someone graduate, you should at least hold a concert or a end of graduation ceremony, but no.. I don't even know what stage will feel like without juyeon, since we never had one since juyeon graduated. But now we need to have a stage without two members that were like the heart of the group. Afterschool is getting older, they can't just leave them alone.

I just wanna say,stay strong Playgirlz.Lets hope for an After School comeback

F(x) the best girl group!💜💜

Both performances left me in electric shock

After school outfits are so on point

To be fair though, that remix of Flashback was kinda clashing with the girls' vocals, no matter how well they sang :/

Back when Flashback was my stripper jam and Blonde Nana was my shit! God I love this era!

F (x) totally won this one,I LOVE YOU F (X)

Afterschool!Jungah I love you..

After School are so gorgeous! Kaeun killed me!

Live stages with remixes are the best, it adds so much more hype, love it. P.S: This is the only stage where the cameraman stayed on Krystal the entire solo, finally someone who gets it!

I'm here because I need an After School comeback in 2016 xD

F(x) did amazingly! :D so proud. Love the dance. Did you hear Luna's fanboys?? Hahaha xD F(x) fighting! After school did a great job too (: but my vote goes to F(x)

F(x) is best！！！

I definitely loved f(x), they are amzing!!!! I REALLY LIKED THEIR SONGS CUZ IT WAS SO CATCHY!!! ALWAYS SUPPORT F(X) 💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕💕

best kpop era ever, sad to see that all these groups were gone now, haizzz

I love f(x) there popularity is so effortless (thanks to SM)... But when i checked AS... I was amazed by these gurls.. They are so talented, i thought before they just one of the bitchy bitchy girl group... But they are not, they really perform well everytime they had singles... I wish they are on SM or JYP, they can be famous as SNSD or even more... Specially Nana such a talented and pretty girl.... And for f(x), i love sulli as an actress, shes really good in acting....

f(x)'s is too colorful... I LOVE IT

This is so iconic! I love both of them and miss this era so much

Nameless Ones! f(x) family Hwaiting!

i like this version of electric shock. the beat change is good

Amber's little ponytail! 😂 💕

AFTER SCHOOL KILLED IT THE BEST DANCING GROUP EVER!!

Fx = a very good group that had a good sound then AfterSchool = a very good group of MODELS that where actually good singers and performers..... I still can't understand why AfterSchool never got super big like SNSD or to a lesser Mamamoo.. These women were all STUNNING

1 is Queen of Concepts ❤ 1 is Queen of Performing ❤ Miss them :((

I miss those two groups soooo much:(((

First, let's forget about their agency. F(x) is quiet unique with different personality each members, while AS the concept sexy with amazing visual and I think their dance much better than f(x) and at least all the member can dance well. Nana is perfect omg how can someone be so beautiful like that

설리 언니 그립다ㅜㅜㅜ 언니 무대에서 완전 이쁘고 귀여운 캐릭터였는데ㅠㅜ연기도 짱이였는데ㅜㅜㅜ 언니 하늘에서 행복해요ㅠㅠ
