Learning choreography separately but coming together as a perfect group, as if no time has passed since 2007! That’s the nation’s girl group GIRLS’ GENERATION 🎉

them practicing in solo/duo showed how important Girls Generation to them. Despite of their individual activities, they worked so hard to find a way to make it work. And it did, the song and album were well-received in charts and physicals. What a successful comeback! 15 years in the industry and still slaying the game. No one's doing it like them!

Yoona and Sooyoung's attention to detail is insane. The audience wouldn't notice those little things for sure but they still pointed them out to ensure that the dance is clean and polished. This is one of the many reasons why they're called The Nation's Girl Group. SNSD is indeed Forever 1 ❤

They weren't lying when they said Sooyoung is a perfectionist and most detailed one when it comes to choreography.

Girls Generation still have it: Visual,Vocal,Choreo,Charisma, Personality,Stage Presence,Hard Work,Aura,Talent. Easily among the best of all time.

I'm having so much fun watching this, seeing them laughing with each other's joke, knowing that they are so busy and tired but seeing them having fun and smiling like that , I'm emotional

Salute to the teacher who taught them the choreo. Having to do it many times over so the girls are supported amidst their busy schedules and the comeback is one thing over others. And to the girls who had to squeeze in a lot of hours amidst all the other activities just to make SONEs happy. And to all the SONEs, Old and New, who, even amidst the life stuff they are dealing with, takes the time to support the girls in their own ways ❤️

Yuri is way too funny for being that talented and beautiful. They were not prepared for the bodybuilding poses this comeback 😂

CAN'T WAIT FOR THE FULL DANCE PRACTICE

I love when the comments are mainly about SNSD, not the individual member. This comeback really is indeed special. Happy 15th soshi, sone 🥳

12:50 the fact that Yuri's joke become a legendary performance during SMTown

That's what you can call a group!! They support each other, not compete with each other or gossip or think one is better and above the others.

FOREVER1 is easily the best Anniversary song EVER!!! They have 2 message in it. 1)GG and SONE always together, FORVER1. 2)GG as a group,is among the best, FOREVER1...Both statement is true!

SNSD literally carrying the whole kpop industry on their backs 🔥😍😍

I didn't expect to see the dance practice behind the scenes after 3 members weren't in SM Ent. Thank you snsd for working hard to meet sone again. You guys did it well !!! Let's meet again in the future, I will always wait for you 💗💗💗💗💗💗💗💗

The patience of the choreographer is outstanding, the fact that she has to teach one by one due to the different in schedules.

7:29 YOONA’s attention to detail is insane. Typically you wouldn’t even ask questions like that but it really matters in the end because it affects synchronicity.

Yuri’s glowing from within, they all do but Yuri’s glow is no joke

Seohyun eonnii will forever be a baby to her sisters. She still makes those cute baby sounds when she's with them. 🥺🫶💕✨

6:36 lmao i lost it when hyo yelled at the doggo 😂😂

Yes SNSD is an all-rounder, singer, dancer, acting, model, visual, idol of idols. Stan attractor!

It’s so crazy how they have to learn it individually and then had only 2-3days to practice it together. These women have worked so hard to give all of us this comeback 🤧 Thank you, soshi for coming back!!

Yuri is so focused in the coreography, she is very disciplined

감히 레전드라 말 할 수 있는 소녀시대도 개인활동 하면서 이만큼 진심이고 칼군무 보여주는데 아직 신인이면서 자기 일에 집중 못 하고 할 일 제대로 못 하는 사람들은 제발 보고 배웠으면 좋겠다... 15년 째 소녀시대만큼 여전하고 대단한 그룹은 없는 듯

2세대 때부터 지금 4세대까지 꾸준히 최정상의 자리를 지키고 있는 유일한 걸그룹 소녀시대. 진짜 대단하고 멋지다. 이게 진짜 걸그룹 근본이자 국민 걸그룹 레전드 걸그룹이지...포에버 원도 다만세처럼 세월이 흐를수록 더 가치있는 노래가 될 거임.

다들 몸 갈아가면서 스케줄 맞추고 연습한게 날 울려... 진짜 다시 태어나도 사랑할꺼야 소시ㅠㅠㅠㅠㅠㅠ

tiffany smiled throughout practice, she had the energy of an angel. I like seeing it. they all look energetic

Seeing SNSD in action is pure happiness. SNSD coaching SNSD is truly admirable. These girls worked so hard for this comeback. I'm so proud to be a SONE and having SNSD in my life.

Learning choreography for a short time (bc of their individual busy schedule) isn't easy but look at them, they've really work hard. So proud of you girls. Thank you for coming back, love u forever! 🥹💗

스케쥴도 많고 서로 시간 맞추기도 어렵고 그와중에 저렇게 열심히 준비하고 완벽한 모습으로 또 나타나고ㅠㅠ 소녀시대 했네 너무너무너무 고생 많았고 고맙고 행복하다 소시 포에버원!

Tiffany saying she was nervous - After all this time?! She’s such a pro. It was so cute 💖

It's the fact that they all learned the choreo separately and still managed to be in sync asf during group practice 😭

멤버들 진짜 안무 하나하나 디테일 놓치지 않고 꼼꼼히 하는 거 너무 멋있다.... 16년차에도 잃지 않는 초심. 이러니 레전드라 불리지....

드디어 올라왔다 안무영상 비하인드ㅠㅠ 좋아 좋다고!!같이 붙어있는 소시만 보면 너무 좋아 그냥 이번주 팬미팅 너무 설렘....녹음실 비하인드랑 그냥 딴 자컨들도 몽땅 주세요 얼른!!!! 12:50 이때부터 시작이였구나...권유리의 집착

I was only aware of SNSD and their significance in Kpop peripherally. But then this 15th anniversary comeback happened and now I am deep into their discography and rewatching all of their past MVs and random live performances from the beginning...what is happening to me?

I love the fact that they dont stop goofing around. They know it’s hard to practice but enjoying the moment with each other is as important.

It must have been so hard for each of them to adjust their schedule for this comeback,I can totally see and feel it 🥺 Seeing each of them had to learn the choreography separately really proves how determined they are in making this worked 🥺 I feel touched and I teared up a little bit knowing that not only us missing them but they too feel the same way. I noticed that Sooyoung has been giving a lot of ideas and some improvements for their choreography and it's amazing to see!! 🤩 I really enjoyed watching them having fun and joking around with each other. I seriously missed it a lot!! 😭💗 Not to mention Yuri and Hyeoyeon have me LMAO!! 😂😂😂 I would definitely miss and treasure this moment a lot! 💗 FOREVER 1 definitely worth the wait!!! 🥺💗 Love you SNSD!! Thank you for working hard and making it happen!!! 💗💗💗

Can't believe how they look this YOUNG at there age. 😲 Seriously,they can put most newly debuted idol in shame. GG forever young, FOREVER1!!!

you cant deny SNSD trully the QUEEN OF VISUAL, even without makeup😍

우리 애들 정말 한결같이 꾸준하게 열심히다 15년간 대단해 팬들이랑 대중들이 5년간 기다린 걸 아니까 더 열심히 하는 거 같지만 그래도 저건 애정이 있어야지만 가능한 건데... 사랑해 얘들아 데뷔 때부터 좋아하길 잘한 거 같다

15 years,SNSD is EVER GREEN!!! They learned choreo alone in short time,yet slayed practice/performance as if they just debuted. Our Nonna/Unnies didn't disappoint. GG/SNSD/SONE FOREVER1!

It's so cool how they learned individually and managed to come together and pull it off

so funny when Yuri was making fun of the "strong pose" and the choreographer said that is the camera on, as if they would care about it... 🤣🤣🤣🤣

The chaos when they gather never goes away 😂 I love them so much

These ladies already 15 years in the industry as a group and still working hard to minute details of their choreography. Well done ladies!

12:49 Muscle Queen Yuri 14:26 Seohyun don't forget Hyoyeon's gift 19:30 Fans' Gift

SNSD proved once again that they are the standard for a kpop girl group. No matter how successful and busy they are due to their individual activities, if everyone is willing, determined and commited for a comeback then they can get it done. Thank you SNSD for this wonderful comeback. From doing your own variety show, appearances on variety shows, radio shows, music shows, doing fansign and fanmeet. We SONEs really appreciate all your hard work, effort and all the sacrifices you've made just to make this comeback possible. Until your next comeback, remember that we SONEs are always here for you waiting, watching and supporting you individually. SNSD and SONEs are FOREVER 1.

I'm going to miss this era soshiiii! We love you so hard 😭💕

드디어..!!!!

legendary girl group indeed, look at how details they were practising and keep on sharing opinion. sooyoung deserves to lead snsd (but taeyeon is our forever kid leader) and the fact that hyoyeon and yoona says 15th years still not sync is funny 🤣🤣😭😭😭 dont they know that their dancing are the one of the most sync in girl group even until now? love them so much!!!

They are all so busy that they can't even gather together to practice and had to learn the choreography individually. It makes me appreciate this comeback even more and thankful to all the members and to everyone who made this possible.

시간 쪼개고 쪼개서 연습하니까 힘들어서라도 적당히 할만 한데 개ㅐㅐㅐㅐ 열심히 하고 하나하나 디테일 맞춰가고ㅠㅠㅠㅠㅠㅠ 소시야 고맙고 고생해써 진짜 너무너무 사랑해ㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠ

수영기가 무대가 너무 그리웠나보다. 열정이 넘쳐. 디테일 하나하나 놓치지 않으려는 모습이 너무 좋다.

they all worked hard. going back to the past is difficult but look they can!! proud

The way they still put a lot of attention on detail is crazy. Thx for the best gift ever 💓

Let just all take a moment and appreciate Yoona's visual at 16:19 . her face spells PERFECTION!

My SONE heart is full just seeing them working this hard despite their very hectic schedule just to give back to us fans. It's not easy but they still made it possible and I'm very thankful as a fan since 2009. We love you GG! #4eva1

Chaotic as always. That's what I miss the most in SNSD 🤣

이렇게 숨은 능력자들이 더 많다는걸 알아주면 좋겠다.

와 안무 하나하나를 저렇게 정확하게 다 맞추니까 걸그룹 칼군무 원조라는 말이 나왔구나....진짜 엄청난 디테일까지 다 맞춘다ㄷ

12:48 Yuri is so naturally funny I can't stop laughing LOL

Such a great friendship! After 15 years, coming together and enjoying themselves. SNSD truly is one of a kind!

I thought Tiffany was Boa at front part of the video😂 I've never thought they assemble each other, but it's ridiculous they really seem similar

Girls’ Generation, Korea’s National Girl Group who knows how to both have fun and still perform perfectly.

The dedication they gave for this comeback is amazing to see. Hope that SM will release the official dance practice to this.

waiting for the Final Dance Practice SM its been a while since we have GG dance practice..thank you SM

Their attention to detail is outstanding! I'm so thankful that they released this kind of detailed dance practice and not the one that looks staged already. I love seeing them having fun when they're together. SNSD

Now this is a real dance PRACTICE!! Thank you!!

22:33 칼군무 미쳤다 ㅠㅠ✨💗 안무동선이랑 멤버들 춤선 넘 예뻐😳💕 안무 연습 비하인드 넘 좋다💖

coming back here because I miss them 😭

This comeback make me love SNSD more and more. Seeing their sacrifice to make this comeback for SONEs. And SONEs don't care about, awards, music show wins or views. All we care about is seeing our idols together singing and dancing and having fun together. Patiently waiting for next comeback even it take another 5 years of waiting.

They are really the NATIONS GIRL GROUP. 15 years later but still slayed it like nothing. GG/SNSD/SONE FOREVER1

I love watching dance practices like this. Like it's an actual dance practice, with members learning the choreography. It's nice to see everyone go through the process and not look all polished.

This video shows how all these beautiful Korean women are TRIPLE THREATS because they are expert professionals singing, dancing and acting. Girls Generation is inspiration to all all around the world of all ages to succeed in our own profession. Love you GG Forever One ❤️! You all are on fire! Whew! ❤️❤️❤️🤩🤩🤩🔥🔥🔥🔥🔥😍😍😍😍 (I love it when choreographer claps her hands to get attention! 🤣🤣🤣🤣🤣 Also may I say the reveals are absolutely beautiful in this choreography. It is spectacular!)

Hard looking dance. These beautiful ladies did an excellent job on the dancing, despite being busy with their individual lives

와.. 우리 언니들 바쁘고 정신 없는 스케줄 속에서도 다같이 안무 맞추고 또 연습하고 또 반복하고 안무 배웠구나ㅜㅜㅜ 왜 영상 보면서도 눈물이 나고 울컥하는지 모르겠네ㅠㅠㅠㅠ + 에스엠 안무영상, 녹음실 비하인드, 활동 비하인드 영상 등 기다리고 있을테니 꼭 올려줘어!!

지금은 소녀시대 앞으로도 소녀시대 영원히 소녀시대 💖 우리 꼭 영원하자 👑

I really appreciate the choreography for being flexible about SNSD members schedules like how hard it must've been to teach them their own choreo based on their lines one by one like without being confused I mean she's used to it and doing it for years but just wow.

15년차 그룹이 연습하는거 봐라 요즘 걸그룹들 안무 하는거 보면 줫나 답없던데 롱런하는 그룹은 진짜 달라도 다르네

와..드디어...안무 연습 비하인드라니...가슴이 웅장해진다...

I love you group SNSD my most favorite, energetic, best, bright, shining, talented, beautiful, charming, perfect, wonderful, amazing and sweet queens girls, we will support and love this group, we are the best, loving and wonderful fans we are always with you, everything is wonderful in this group and the participants are talented in everything, I am very glad that I am their fan and proud of it, wherever they are, we are always with them, Stan and Love SNSD.

I remember after GEE, their schedules has been so hectic that the girls were taught dances individually the only time they practiced as full group was when nearing their CB... because YOONA has been acting, the other girls are busy with endorsment deals, plus they also need to take care of their KYUNGSAN 😂...

Indonesia loves Girls Generation!

SNSD really worked as much as active idols for FOREVER1. It shows there dedication and love for SONE,they really wanted to give there best for anniversary.

안무연습 비하인드 영상 넘 좋다 🥰 칼군무 진짜 미쳤다...

I am speechless… The more i look at these girls the more i am amazed at their natural way of being so simply gorgeous. I am really lucky to be a SONE... forever1 💗💖💙💚💝💛💜💟

Nation's GirlGroup

Learning the choregraphy seperately but managing to dance well EVEN MORE at the stage, is no wonder GG.

SNSD is a prime JEWEL in a crown of K-POP

난 이 언니들이 숨만 쉬어도 재밌어...

When you see a final product, there a times when you forget just how much work actually went into making it. Watching this really does remind of just how much hard work and dedication really does put things into perspective. That being said, super stoked that GG is back!

8월의 시작부터 끝까지 소녀시대와 함께 할 수 있어서 행복해요💘 15년째 8월이라는 평범한 한 달을 특별하게 만들어줘서 고마워요 안무 연습 비하인드 보면서 8월도 힘차게 마무리하고 우리 팬미팅에서 건강하게 만나💘

소녀시대 클라스 오지네 와....

OMG The details 🥵Forever 1 our SNSD💝🫰🏻

Hyoyeon: Focus guys, focus! Hyoyeon 5 seconds later: 20:50

다들 프로미 물씬ㅠㅠㅠㅠ 하나하나 정확히 짚어가면서 집중하니까 본업은 정말 다르구나 싶고 멋있어 완벽해...

18:20 when the instructor had to call out "Hello, Hello" because Yoona and Hyoyeon were goofing around at the back 😂 nevertheless, it's nice seeing how soshi can still have fun and laugh with each other while practicing for hours to perfect the movements. Now i'm waiting for the full dance practice video ❤️

12:53 In the end they really do the changed-choreography for their stage performance. Thanks Yuri 22:00 Sooyoung always become the detailed-one

I love how they're having fun learning new choreography. The members were also giving their opinions and suggestions to enhance the choreography.

seeing them together like this again gives me so much comfort and my heart gets warm
