Trying to let you know
Sending you a sign, sending a signal
I must let you know
Sending you a sign, sending a signal

Sending you a sign, sending a signal
Sending you a sign, sending a signal
Sending you a sign, sending a signal
[DA/CHAE] I must let you know

Sending you a sign, sending a signal
But it won’t go through
Giving you a look, trying to make you notice
But you don’t get it
I’m so frustrated, going crazy
I don’t know why this is happening
I’ll gather up my strength once more and
[MO/MI] Send you a sign, send a signal

My looks, my gestures, all my facial expressions
There’s no use, nothing works
You have no tact at all
How much more can I express my feelings?

From some point, I started liking you
You fool
Why don’t you know my heart?
When are you going to stop being so dumb
And only treat me as a friend?
‘Cause that’s not what I want

Sending you a sign, sending a signal
Electric electric electric electric
I want you, I want you
But why aren’t you reacting?
Every time we meet, with all my heart
Electric electric electric electric
I’m waiting, you can see everything
But why don’t you know?

Trying to let you know
Sending you a sign, sending a signal
I must let you know
Sending you a sign, sending a signal

If I look at you and smile, you should know
I’ve already looked at you and smiled so many times today
If I keep talking to you, you should feel it
I keep staying by your side

Why don’t you know my heart?

근데 전혀 안 통해
눈빛을 보내 눈치를 주네
근데 못 알아듣네
답답해서 미치겠다 정말
왜 그런지 모르겠다 정말
다시 한 번 힘을 내서
[MO/MI] Sign을 보내 signal 보내

눈짓도 손짓도 어떤 표정도
소용이 없네 하나도 안 통해
눈치도 코치도 전혀 없나 봐
더 이상 어떻게 내 맘을 표현해

언제부턴가 난 네가 좋아
지기 시작했어 바보야
왜 이렇게도 내 맘을 몰라
언제까지 이렇게 둔하게
나를 친구로만 대할래
내가 원하는 건 그게 아닌데

Signal 보내 signal 보내
찌릿 찌릿 찌릿 찌릿
난 너를 원해 난 너를 원해
왜 반응이 없니
만날 때 마다 마음을 담아
찌릿 찌릿 찌릿 찌릿
기다리잖아 다 보이잖아
왜 알지 못하니

널 보며 웃으면 알아채야지
오늘만 몇 번째 널 보며 웃는데
자꾸 말을 걸면 좀 느껴야지
계속 네 곁에 머물러있는데

언제부턴가 난 네가 좋아
지기 시작했어 바보야
왜 이렇게도 내 맘을 몰라
언제까지 이렇게 둔하게
나를 친구로만 대할래
