I didn't know this before watching the making video but they actually didn't film together at all. They filmed separately in China and Korea. That is so freaking cool.

Just in case anyone here don’t know much about XIN Liu (Liu Yuxin) She’s a singer-songwriter from China and was debuted as the first place (Center) of the variety show Youth with You 2 in 2020. She’s now graduated from the team and is a solo female singer✨ She’ve launched her first full long album named 《XANADU》that includes 10 songs, 10 MV and 10 types of dance. In this coming Summer season, she’s the First Female Caption of Street Dancers of China, and also having 3 others variety shows such as E-pop of China, Jiayou GanFanRen and etc😻

'Better' is already a masterpiece in korean, and having this version with xin liu...... something has, yet again, awaken within me. all im seeing is a spectrum, both at ends. DAMN THESE WOMEN. I LOVE TALENTED WOMEN.

Liu yu xin is really a very cool girl. I got to know her while watching on an idol survival show. she really have the talent. Tbh I love how she redefine the female gender and she's among a few female idols I admired alot in the industry.

Idk but making XIN sing this kind of song with a legend like Boa performing by her side it's just revolutionary. Both of them broke stereotypes since the moment they debuted.

XIN LIU (LIU YUXIN) is a SOLO ARTIST and is currently the BEST-SELLING FEMALE ARTIST in CHINA both in PHYSICAL AND DIGITAL SALES

BoA in white: pure, refreshing yet powerful and confident. XIN in black: cool, neutral yet beautiful and capitative. Such satisfying collab!

このXINに惚れてファンになりました❤これからも世界規模で活躍して下さい❤

BoA and XIN isn't only Dancer and Singer , They are actually MULTI-TALENTED IDOLS.........!!!!!!

I’m so happy that Liu Yuxin is becoming more and more popular. Love her so much. Our X queen

Vocals are ON THE POINT. Dance is ON THE POINT. Visuals are ON THE POINT, Literally EVERYTHING is ON THE POINT!!

After Paris Fashion Week come here to see all XIN's performs and MV.. this is amazing collabs 🔥🔥🔥🔥 both of 👑 are ACE!

BoA has long hair and a white dress; XIN Liu has short hair and black leather pants.It really matches the Chinese title of "Better" from the beginning🤙🏻Btw..XIN is really beautiful🥰💙💙💙

I hope Xin can also focus her career outside of China. She have so much potential and she can do almost everything you can imagine.

I'm here again since XIN performed this on her solo concert 😍 she did AMAZING!!! There's a part in the choreography wherein they could have slayed it together if BoA was there... now I'm wishing they could meet in the future somehow and give us that moment 😂🤩

Can we talk about how we never thought of pairing them together and now we see this collab, it's absolute perfection? The chemistry and balance ??? Like THANK YOU WHOEVER MADE THIS HAPPEN

This just proved that XIN's finally getting the recognition she deserves! SLAY QUEENS 😩😩

yuxin is a dangerous girl，I can't help watching her dance and sing，her isolation is perfect. she's a genius

Liu xin is awesome, mind-blowing. She knows how to show herself in front of the camera and her dance... literally no words I started doing dance when I watched her in sdc5. I am from India but still love you I hope you always do your best and also show ur talent across the world not only in china because you have that potential.......love you from INDIA

The Queen of Kpop with The Queen of Cpop!!! What a legendary collab!!

I never thought I will see Liu Yuxin collaborating with a kpop artist. Both of them are amazing artists and fantastic dancers!

XIN is a professional dancer and singer. She has been dancing popping for over ten years. LOVE THIS COLAB

I don't know BoA and Xin before.. But fortunately, I found Liu Yuxin through Youth With You (sorry for the 3 years late 🥲), and now searching for all video of Liu Yuxin 😂💙 Nice collaboration, you two are awesome 👏🙌

I mean XIN's isolation is insane!!!! I have to say I LOVE POWERFUL dance moves!

Can i have an oxygen??? I can't breathe OMG both are slay😭😭😭 Both Queens on fire😭😭🔥🔥🔥 Liu Yuxin Mama ai ni❤❤❤😭😭

XIN LIU AND BOA ARE BOTH SLAYING!!!! THEY ARE THE HONESTLY THE BEST COMBINATION 😩😩😩

100 Million views on Weibo Yay!!!! I'm really really really really hoping that BoA and Yuxin will sing Better Chinese version, Live 💛💙

Everyone agrees that Boa is a genius and a full package artist, but can we talk about liu yuxin! She's AMAZING AND SO TALENTED!!😍😍👌🏻

For all confused souls This is the CHINESE version of BoA's ORIGINAL song Better which was released (in Korean) before Collaboration with China's BEST SELLER FEMALE IDOL- LIU YUXIN who's a SOLOIST 💙

Never heard of her before but Xin Liu's presence is mindblowing. It's impossible to look away. Really liking the voice too.

I noticed Xin in Youth with you S2 and I watched that coz of Lisa , but Xin stole my heart just in first ranking show. Since that time, she never let us down..

has anyone mentioned that？before learning to be an idol or a singer，she was a professional popper，and thats why her dance is sooooo amazing

Xin Liu fans from Malaysia come for support 🙌🏻 C-POP ACE x K-POP ACE collaboration are so amazing and lit! Hope can see them performance on stage together in future 💃🏼

OMG the editing of this video is insane! Thought they really danced together 😭😭😭 My queens slayed this!!! Hope BoA and Yuxin can meet in person someday!

Xin Liu........ awesome

This is a Real masterpiece! See how these two girls perform the beauty of conflict!! XIN LIU is damn attractive in her move and her eyes are just so catchy, leading you to follow her move!!! I’m so in love with her! And,,,,,her FACE is just soooo pretty.

The timeless K-Pop Queen, Icon & Legendary BoA really has no competition in the game, she's her own game, she's her own league, she's one of a kind, she's seriously out of this world. Now that she's brought back her Chinese singing ability is just super insane, nothing this woman can't do forreal. The collaboration would have been better than this if BoA & XIN could meet irl but we could see how they both slayed here. The rare cultural exchange by actual K-Pop & C-Pop artists despite of the pandemic and political issues. Congratulations to both BoA x XIN 🔥👑💛

Here for this amazing collab between Queens BoA & XIN💙 Love the monochromatic colour scheme of this MV

I didn't know Xin before this collab but wow, she is an incredible performer! Her presence is amazing!

They slayeddd. You've come so far Xin! That summer is remarkable afterall

This duet was so unexpected! I am so glad to see BOA and XIN LIU collaborating together!!! SLAYED QUEENS 👑

Thank you Liu Yuxin for all of these surprises 💙🥺 You both slays this collaboration

It's already over 96 Million views on XIN's weibo account and Ah Xin, the vocalist of Mayday (a legend Taiwanese band) knows this song! I'm so happy!!! 💙💛👑👑

Liu yuxin she's a real goddess her voice tho😇 the song is really perfect 🥰 Give a lot of love and support to both BoA&LiuYuXin ❤ Hope to see more collaborations 🙏

Xin and BoA's voices go really well together

XIN is one of my favourite artistes of all time because she’s so talented and so cool, really so proud to see all that’s accomplished in the last 2 years

二人ともカッコいい。日本でコンサートやって欲しい🙏

Two QUEENS from different kingdoms with equal caliber and power! Who would've thought we get a collaboration we never knew we needed.

Coming here for Liu yuxin.. but really have to say both queens are legend in their own league. This collaboration is 😍😍😍! Jiayou yuxin! Your hardwork is paying off! Finally a bigger stage to show your talents!

XIN Liu with BoA makes so much sense. They both together just fits so well. This is an amazing collaboration!!

Xin is so cool, i think i fell in love a little

看過刘雨昕的舞台，就會知道她的唱跳實力有多吸眼球💙

THIS IS FIRE. YUXIN'S CHARISMA IS NO JOKE AND THE QUEENS SLAYED

They both are talented and gorgeous Hi Xin Liu...my cpop queen, she's absolutely stunning and talented, not only can sing rap and dance well, but she can produce and compose music too, beatbox and playing some music instrument too

Like xin, her move sharp with power, i believe she can dance more powerful dance like male move. And she look very cool. Like it.

Yuxin got the best singer and dancer award in Tmea China event , deserved to have this collaboration with A legendary BoA Best of Asia Queen with X Queen Liu YuXin a rising star Asia ♡ Very proud of U XIN!

Both Xin & BoA actually filmed this MV in China & S.Korea separately! My interpretation of the “destruction” in this MV might represent both of them breaking boundaries and overcoming differences (cultural/language barrier/generation), ultimately reaching a common ground, combining the best of both worlds (Cpop & Kpop)

A solid argument could be made, at this point, that BOA is one of the most talented idol in K-Pop history.

if boa will collaborate more in liu yuxin by releasing albums or songs, easy money for sm, liu yuxin is a superstar and has a strong fanbanse in china.

I did NOT expect THIS Xin is a great dancer and all it's just that I just didn't expect her to collab with queen Boa but 🅓🅐🅜🅝 After so long Boa is still making music and Xin looks absolutely gorgeous?!

WOW this is Liu Yuxin the new captain and the only female captain in SDC5 I thought she was only a popping dancer so she is also a singer, I was looking forward to her in SDC :-):-):-)

BOA AND XIN BOTH SLAYED

Better Collaboration MV has over 90 Million Views on XIN's weibo account 💙💛

Xin will have her first world stage show-Coachella on April 14!!! Cant't wait to watch

Please, I need them performing this live together..

Other than the great BoA, I just want to praise Yuxin, I was captivated by her since qcyn2 and was happy that she debuted as center of the9. Now, she collaborated with such big artists of the industry, so proud of Yuxin!

Can’t help falling love to XIN

What a song! BoA is the Queen! If she chose Xin Liu for a collab of one of her most recent tracks, there's a reason. At this point, I root also for her breakthrough in the SK market. Fighting!

This has to be performed at MAMA this year.

What's better than one? TWO all rounders having a collaboration! Surreal collab, love the music and stunning MV! No words omgg

First time I saw her. I immediately fell in love. XIN

夢幻聯動!!! 兩個舞後的合作曲真的太精彩啦 希望將來有機會可以看她們一起上台!

Bg info from a song critic Lee Soo-Man heard Yuxin's last yr and felt that Yuxin is the new gen of "Asia's new star". Her singing & composing skills, prof dance level and impressive stage performance made SM decide to do this collab. BoA BETTER WITH XIN #BETTER_BoA_XIN

This collab is a big surprise and pleasure for eyes and ears. I am so happy for Xin

I really thought Xin went to Korea to film this. After watching the bts, I appreciated this MV even more. It's so amazing how SM did this! And Better is such a BOP song!!

I am the biggest fan of Youth with You and voted for Xin Liu throughout the duration of the show. I am really hoping she get the exposure she deserves since the debut of THE9 didn't really give justice to the girls and was not promoted as much, so the hype of YWY died down together with their popularity internationally. I really hope this is a start of a new beginning for her and I also wish she'll get to collab with Lisa again in the near future. Fighting!!

OMG Boa and Xin are gorgeous and super talented!! The dance moves is so clean, voice also beautiful.... I stan the queens!!

it’s actually insane how big of a collab this is for Xin i’m so happy for her

i. can't. get. over. how. liu. yu. xin. is. making. me. feel. things

I WATCHED HOW XIN LIU IMPROVE AS AN IDOL DURING THE YWY2. SEEING XIN NOW WITH THE LEGENDARY BOA, MAKES ME SO PROUD AND HAPPY. SO HAPPY FOR THIS COLLAB!!! BOA AND XINLIU SARANGHAE

I have always loved Xin ever since I watch Youth With You. She is hella talented 🔥. So happy to see her Collab with K-pop queen Boa. I hope liu yuxin do more projects internationally and not just in China. Her talent deserve recognition from all around the world

They should have another collaboration with powerful dance move and vocals. Because this two are QUEENS. and they can slay both.

I've loved Xin since Youth with You😍😍😍😍😍

BoA = the only female judge for STREET MAN FIGHTER Liu Yuxin = the first female captain STREET DANCE OF CHINA 5th season Looking forward to the two QUEENS 👑👑

Song now had a total different vibe with Xin included. Thank you Boa for adding her , also Boa always comes with original ideas unexpected i love her .

Can't be BETTER than this! BoA and Yuxin (XIN) Liu accomplished a great collaboration!

雨昕臉真得很美 一開始看到Boa×Xin以為是SM新人 後來發現原來是雨昕 這首真得超好聽好看

Xin Liuuu

Congrats for being nominated as best collaboration in APMA 2022!

I don't want it to end. I am so greedy. I want the live stage, solo cams and also the performance video now. And thank you Queens for serving us with this jam.

Xin has a very beautiful voice, and her control of it is way better here than when she was a trainee in Produce.

X Queen make us crazy!!!

This is crazy, combination of 2 QUEENs is out of this world. Yuxin, my girl, I fall hard for u this time again.

I don't know who Xin is but I love her style and voice! I already loved this song but BoA and Xin together made it even better!

Congratulations on hitting 100 million views on Weibo!

Liu YuXin is so cool in this video. Hope that she is focusing more on overseas market in the future.

MY GOSH🤯 the editing is SUPERB! Bet you guys didn’t know both of them never filmed together at all, but is able to incorporate so well. The expressions and moves are really executed perfectly. Anyone notice the dance part where BoA went down, but Yuxin remain up. The details are on point!

劉雨昕真的好棒啊😭😭😭希望有越來越多人看見這個很有才華的女孩！！！！！

They are extremely in sync so the editor can even edited them dancing together, awesome

it's been weeks and I'm still watching this.. Really can't believe Xin collaborating with BoA under SM so proud of her💙
