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 🎉

CAN'T WAIT FOR THE FULL DANCE PRACTICE

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 ❤️

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 ❤

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

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

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

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

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!

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!

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

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

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

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.

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.

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

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

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

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 💗💗💗💗💗💗💗💗

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’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!!

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

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

드디어..!!!!

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

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

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.

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

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

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

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

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! 🥹💗

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

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

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

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

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.

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.

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

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!!

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

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

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

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

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

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!

2 :01 taeyeon is back with her ahjumma laugh . wahhh. you can really feel how taeyeon laugh shows how happy she isss

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!

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

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

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.

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

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

난 이 언니들이 숨만 쉬어도 재밌어...

the very first girl group that got me into kpop 🥰 snsd you'll ALWAYS have a special place in my heart. what i wld do to go to the smtown stage to watch their cb stage live 😭

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

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

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

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

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

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

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

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

지금은 소녀시대 앞으로도 소녀시대 영원히 소녀시대 💖 우리 꼭 영원하자 👑

와..드디어...안무 연습 비하인드라니...가슴이 웅장해진다...

이렇게 숨은 능력자들이 더 많다는걸 알아주면 좋겠다.

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.

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

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!!! 💗💗💗

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

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

이런영상 너무 좋다 ㅠㅠㅠ 그냥 보고만있어도 행복해져

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.

It's nice seeing the behind the scenes of the amazing choreography. A raw glimpse to the hard work, details, and attention it goes into it rather than dance practice video that doesn't show the natural environment of a practice session.

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... 🤣🤣🤣🤣

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

안무연습 비하인드 영상 넘 좋다 🥰 칼군무 진짜 미쳤다...

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

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

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.

너무 좋다 이렇게 함께있는 모습ㅜㅜ 너무 소중해…. 소녀시대 사랑해💖

보기만 해도 흐뭇한 영상 다들 바쁜데 열일해준 소원 고마워 융 화이링

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

소녀시대 클라스 오지네 와....

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

소녀시대 팬들위해서 저렇게 춤추고 노래해주는거 최고임👍💖💖

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!!!

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

안니들의 웃음소리 진짜 좋다💗 소원까지 웃게 해줘서 고마워요 덕분에 행복해

이렇게 피나는 노력이 있기에 지금의소녀시대가 있는듯 너무 대단해~ 이런영상 많아서좋다

아 정말 왜 이렇게 감동이지ㅠㅠㅠ 언니들이 개인연습하고 일일이 시간을 내준 거에 1차 감동 같이 모여서 연습하는 거에 2차 감동 디테일 잡는 거에 3차 감동ㅠㅠ 왜 소녀시대는 모여있는 것만으로도 감동이지ㅠㅠㅠ 너무 좋아요 진짜ㅠㅠㅠ 내 청춘에 함께한 소녀시대여서 그런지 무한감동 무한응원ㅠㅠㅠㅠ언니들 진짜 진심으로 고맙고 사랑해 제발 평생 함께해 소녀시대!!!!!!!!!!!!!!!!!!!!

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!!!

The most hardworking group since debut. I am so proud of you my SNSD 🤗

소시 안무연습 영상보고 웃고 울고 다 하는 난 뭐지 ㅠㅠㅠㅠ 각자 연습하다가 다같이 모여서 안무 맞추는거 보고 울컥 ㅠㅠ 역시 소녀시대야 💖 스엠 빨리 풀영상 풀어줘요!!!!

I've been SONE for 10 yrs and YoonAddict for 12 yrs, but this is the first time that I learn that there is such a thing as "Yoona rythm"....Learn something new.... Thank you for uploaded this vid... now we're waiting for MV dance ver or full dance practice vid....:)

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

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💘

I'm not a fan of SNSD but I look up them so much that's why I watch all their forever 1 stage and also this. I'm a second gen stan of CNBLUE my one and only, I'm not into dance idol before but since I watch my cn boys every music show and music awards that is why I know snsd and for some reason it makes me feel so nostalgic 😭 They all grew up so beautiful and amazing people. I'm going to miss them. Girls Generation legacy will be Forever~ Vocals, Dance, Visual, character, everything. SNSD is a complete package. Thank you for coming back. Please be healthy the best of all the best. Girls Generation you all did well.

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 💗💖💙💚💝💛💜💟

Hyoyeon's ability to pick up the choreography will always amaze me
