the things I noticed (opinionated) in this live performance... 1. Taeyeon actually looks happy. 2. Jessica is often looking down. 3. The way Taeyeon looks at Jessica, and how she removed her earpiece to listen and sing along with Jessica in the second chorus. 4. Tiffany's 'adlib' is...ugh. I don't know. I don't want to talk about it. 5. Seohyun's voice in the background is so loud to point it doesn't harmonize with the others. Or maybe it's her mic's volume. 6. Taeyeon and Jessica's voices...AWESOME! HEAVENLY! 7. Taeyeon and Jessica made this song actually and almost look like it's their duet. 8. Taeyeon - Jessica - Seohyun. One of the most should have been's. 9. And of course, once again, a Taeyeon and Jessica duet should have happened in every album. Or single. Or live performances. Or how about every time? TaengSic! TaengSic! How I wish...

Look at Taengsic in the last chorus. That's the reason why I ship them.

i love how Jessica sing. like her hand gesture is so beautiful.. i love this song! kinda wish sica n taeng sing this song in duet, really love their voice..

things scientists still can't explain: 1. the big bang theory 2. taengsic

TaengSic's vocal are the best! 👍👍👍

reason why we cant hear tiffanys adlib at the last chorus is because taeyeon and jessicas voice are too powerful. love of taesic ❤

I dont know, but I wish this song just sang by jessica and taeyeon :' their duet song

I love how Taeyeon's enjoying this song so much, especially during Jessica's parts. 💕

jessica's voice im melting~~

Look at my taengsic. I love how taeyeon sing with Jessica in the chorus without the mic. And their adlibs are lit. 💕

Taengsic's style when singing! They slay this song

Really love Jessica's voice. Hope she gets to sing more in the future. ♥

this is my fav song of their last album. love it when jessica and taeyeon are doing most of the singing. love jessica's voice the most.

2:00 you can see how taengsic carried this song, i wish there would be duet project for them, i miss them so much :'(

DAMMIT JESSICA. SLAAAAAAAAAY. I LOVE GOODBYE LIVE SO MUCH

2:12 lmao taeyeon don't make it too obvious you're enjoying taengsic more than anyone of us does

@2:45 I love how Jessica changed it to high note when originally it was supposed to be low! ❤❤

really love sica voice especially in snsd ballads.. and the best thing ever is really love to see taesic duet together.. and really love the way tae looking at sica when she singing.. feeling taesic again..

Omg taengsic's highnote at 2:07 ♡

really like jessica's sweet voice. taeyeon also good.

Just love jessica voice her personality everything

Taengsic ♥ beautiful melody

her voice make me feeellllll..I can see TAENGSIC

Thank you so much for sharing! Jessica is the one who makes me addicted to kpop! I love her unique voice!

I didn't I was here a week ago. I'm so addicted to this song. Jessica's voice. Ugh. I love it so much!

The last chorus sounds like a taengsic duet :)

taeyeon and sica hard carried this song but now jessica is gone :(

Taengsic voices blend so well together..

2:06 taesic duet

My first time attending a concert with GG, also the last HK concert with GG which is with Jessi

I can't unsee Taeyeon singing with Jessica.And still people jump on her head /facepalm/ goodbye is one of my fave G songs.Good performance!

Love you Jessica forever, you're so cute and gorgeous!!!!💟💟💟💟💟💟💟 fighting!!!!

I love how Jessica change her voice from falseto into her really voice cause the mic dont really supportive :")

Nawww tae laugh when sica was singing taengsic feelings

1:17 i love this part😍😍

Taengsic feels is strong in this song 😣😭

Taeyeon seems enjoy this performance

You can see Taeyon loves hearing Jessicas voice

Tiffany is being too loud in the chorus...you can hear something sounds wrong, too sharp. Other than that at 2:06 Taeyeon and Jessica voices sound absolutely beautiful!

Taengsic is so... I can't explain it 🥺💖

I've always been a SONE, and I've always admired the girls' talents even they have so many bashers. And when it was announced that they're going to have a sub-unit, I have been looking forward for Taeyeon, Jessica, and Seohyun., but then it was TTS. In my opinion, TJS could have been better. :D

Jessica was fixing her hair but she really was looking at Taeyeon you can see it in the last minute.

Jessica's voice really compliment taeyeon's period!😍 This should be their duet😍

The background part during the chorus is higher as compared to the original right? And damn without jessica this song is really different :/

sica~thank you

TTS should have been TJS (Taeyeon, Jessica, and Seohyun) to begin with. If you go back to the classic songs by SNSD (Into the new world, Baby baby, Kissing you, etc.), you'll notice that these 3 girls did more singing parts than either Tiffany or Sunny did most of the time.

i think taeyeon just smile or smirk after she heard that she and jess just had a unintentional duet in the last chorus part (2:10 - 2:14) they really dominated the last chorus and its legendary. why cant sm... !!! i juts think that taeyeon represent those who are watching this video and heard the duet of taengsic hahaha we had similar reaction tae after we heard the last chorus part 😊

TJS (Taeyeon, Jessica, Seohyun) the subunit we always wanted and never got 🥺

Love you and miss you so much Jessica ❤️

TAEYEON , JESSICA

Now that's singing...you can see it in her face...nowadays most idols barely even move their mouths

jessica 's right face is good looking

I think 2014 was the comeback of Jessica's real voice. Coz since 2009 shes been doing musical angd so.. Got tired and all..overused. but in 2014, the sica's voice is like her 2007 voice with much more improvement.

sica

taengsic are so enjoy...

Better times 😔. Still hope one day they'll all come along. 😁

ITNW, Complete, and most especially Goodbye really flexed TaengSic Harmony....

It's nearly 2021 now I still miss themmm!😢❤

Taeyeon too cute!!!!!!!

2:40 이부분 제시카 목소리 뚫고나오는거 소름ㅠ

No wonder Jessica Jung was noticed and included in Parasite the award winning movie🎥

I'm not being bad but I like Tiffany to move her mic because she was being too loud. We could hear that there was something off.

jessica jang 😍😍

Damn it, Taengsic! Why do you have to do this to me?

just taengsic

Jessica😍

Taengsic were so powerful here ❤️ btw taeyeon why were you smiling while you were singing 💕

I'm here again for taengsic harmony. Miss them both 😭

Jessi. Taeng. Perfection

Remember when Jessica said that there are times that Taeyeon and Jessica need to sing higher and louder than the others and it was really hard? That she feels sorry for Taeyeon because of it? Well I just remembered it now. I always remember what taengsic says.

Jessica comeback :c

what the heck is that tiffany's voice leading when taeyeon and Jessica singing the chorus? like WTF girl?! maybe you're jealous cuz you don't have that long part like taengsic's chorus thats why you are making your own version

taengsic

Taeyeon Seohyun and Sica shouldve been the sububit or taengsic duet. Then tiffany couldve been the one who debuted Solo first. Her voice is so distinct and western in tone. Plus her vocal technique cant blend with the Taeyeon's technique. She shines more if only SM new how play her strengths as a soloist but nevertheless, Tiffany is doing good outside sm now.

gorjess.......... taengsic kekekekeee

Seohyun ❤️

oh my TaengSic 🥰😍🤩❤💟💕 love both

Taengsic ❤

Now, a proof. Taeyeon doesn't have any involvement in that kicked out. This time, they were close again considering how taeyeon said sica's name in TTS.

So beautiful!

Why is it that I feel like Jessica was really lonely and isolated by the other girls at this time?

Miss jessica

Jakun UI bangey wkw Aaaa I MISS JESSICA SO MUCH 😭😭😭

The most replayed taengsic duet 2:04

2:42 the tiffany is so envious, Jessica extended her line and she out of nowhere extended her "oh yeah" just to want to tease Jessica

"Tittfany", why do you have the spoil a good performance of your teammates? If you can't make it better, please don't make it worse.

Sicaaaaa

There's someone ruining the song and it's not the one in the shot, it sounds like Tiffany i'm not sure

wahhh...guys 3:07 .... jessia look at taeyeon and taeyeon smile to jessica

I wonder if sica kept that ring until now

Sometimes tiffany's voice is so annoying. And sometimes its just too loud. (just sayin') NO HATE

Tiffany's voice in here was kinda 💀. It was kinda ruining the song I really like. I mean we should cherish all the taengsic since there's no more. It sound like she was trying to harmonize but she couldn't. It just made it worse and her adlibs are like a no go.

Kim.taeyeon.oh.my.god

I really love Seohyun..but that time i wish, shes standing beside hyoyeon so that..my taengsic heart..

the visual is no joke

I miss OT9

TaengSic😭😭👀

2:07 2:07 2:07 2:07 2:07

i miss taengsic;)

Seohyuuun
