Korean:

내 생각에 맘이 아파 밤을 새?
니가 날 걱정해? Wow
처음 듣는 얘기

혼자 갖은 착한 척
나 땜에 눈물 나는 척
너의 모든 SNS 애쓰네
너만 상처 받은 얘기

이미 지나 버린 지워 버린 시간 속에
불러 주던 My name 한땐
너무나 반짝였던 너와 나
간직하려 했던 화려했던 추억 다
너는 뱉어 멋대로 뱉어
차갑게 뱉어 Oh oh oh oh woah

You think you’re real cool
You think you’re real coo-oo-ool 
니 생각일 뿐
{Taeyeon/Sooyoung} Boy, you ain’t cooler than me, nah
You think you’re real cool
You think you’re real coo-oo-ool
니 착각의 끝
{Taeyeon/Hyoyeon} Boy, you ain’t cooler than me, nah

처음 듣는 얘기

Ha yeah 어느새 또 우리 얘길 들춰내
사람들이 널 집중하게 이용했어 날
가시 돋친 Bad girl 떠들어 대는 걸
적당히 눈감아 주니까 또
선을 넘어 넌

자꾸 흐려지는 느려지는 구름 아래
쏟아지는 My rain 속에
나 홀로 감춰 흘린 눈물과
내가 받은 상처 보란 듯이 너는 다
모두 뱉어 가볍게 뱉어
우습게 뱉어 Oh oh oh oh wow

You think you’re real cool
You think you’re real coo-oo-ool
니 생각일 뿐
{Taeyeon/Yoona} Boy, you ain’t cooler than me, nah
You think you’re real cool 
You think you’re real coo-oo-ool
니 착각의 끝
{Taeyeon/Tiffany} Boy, you ain’t cooler than me, nah

Boy 자신 없음 Back uh
이제 와서 왜 아련히 날 보니 아 뭐니
제대로 말해 What what what
기를 못 펴 왜?

니가 멋대로 막
써 내려간 가십 속의 Bad girl
괜찮아 뭐 결국엔 다 네게 Return
똑똑히 좀 들어 내가 한 선택
후회할 맘 더는 없어 Go away

온 세상이 너 하나뿐인
줄만 알던 나 아냐
더 분명한 답 너에게 난
미치게 아까운 여자란 걸
Because

You think you’re real cool
You think you’re real coo-oo-ool
니 생각일 뿐
{Taeyeon/Yuri} Boy, you ain’t cooler than me, nah
You think you’re real cool 
You think you’re real coo-oo-ool
니 착각의 끝
{Taeyeon/Yoona} Boy, you ain’t cooler than me, nah

English:

Do you think your heart aches thinking of me all night?
You’re worried about me? Wow,
That’s news to me.

Pretending to be all good on your own,
Pretending to cry because of me,
You’re trying hard on all your SNS,
Stories where only you got hurt.

In the time that has already passed, erased,
Where you used to call my name, once,
You and I shone so brightly,
The glamorous memories I wanted to keep,
You just spit them out, carelessly spit them out,
Coldly spit them out, Oh oh oh oh woah.

You think you’re real cool,
You think you’re real coo-oo-ool,
That’s just what you think,
{Taeyeon/Sooyoung} Boy, you ain’t cooler than me, nah.
You think you’re real cool,
You think you’re real coo-oo-ool,
The end of your delusion,
{Taeyeon/Hyoyeon} Boy, you ain’t cooler than me, nah.

That’s news to me.

Ha yeah, somehow you’re digging up our story again,
You used me to make people focus on you,
Talking about the thorny bad girl,
Because I turned a blind eye somewhat,
You crossed the line again.

Under the clouds that get blurry and slow,
In my rain that pours,
The tears I hid and shed alone,
As if to show the wounds I received, you just,
Spit it all out, lightly spit it out,
Ridiculously spit it out, Oh oh oh oh wow.

You think you’re real cool,
You think you’re real coo-oo-ool,
That’s just what you think,
{Taeyeon/Yoona} Boy, you ain’t cooler than me, nah.
You think you’re real cool,
You think you’re real coo-oo-ool,
The end of your delusion,
{Taeyeon/Tiffany} Boy, you ain’t cooler than me, nah.

Boy, if you’re not confident, back uh,
Why are you looking at me wistfully now, what?
Say it properly, What what what,
Why can’t you stand tall?

You, carelessly writing,
The bad girl in the gossip,
It’s okay, in the end, it all returns to you,
Listen closely to the choice I made,
I have no regrets anymore, Go away.

The world isn’t just about you,
I’m not that person anymore,
A clearer answer to you is,
I’m a woman too precious to lose,
Because

You think you’re real cool,
You think you’re real coo-oo-ool,
That’s just what you think,
{Taeyeon/Yuri} Boy, you ain’t cooler than me, nah.
You think you’re real cool,
You think you’re real coo-oo-ool,
The end of your delusion,
{Taeyeon/Yoona} Boy, you ain’t cooler than me, nah.
