Cupid歌词：
불꺼진 romantic all my life
내 주위는 온통 lovely day
내 눈 속에 비친 arrow sign
Oh why oh why oh why oh why
I'm feeling lonely lonely
그만 힐끗대고 말해줘요
Hold me hold me
다시 crying in my room
숨기고 싶어
Say what you say but I want it more
But still I want it more more more
I gave a second chance to Cupid
널 믿은 내가 정말 stupid
보여줄게 숨겨왔던 love is it real
Cupid is so dumb
또 꿈길을 걷는 everyday
눈 뜨면 다시 또 flew away
Waiting around is a waste waste
나 솔직히 지금이 편해
상상만큼 짜릿한 걸까
Now I'm so lonely lonely
매일 꿈속에서 연습했죠
Kiss me kiss me
다시 crying in my room
포기할까봐
Say what you say but I want it more
But still I want it more more more
I gave a second chance to Cupid
널 믿은 내가 정말 stupid
보여줄게 숨겨왔던 love is it real
Cupid is so dumb
I'm so lonely hold me tightly
짜릿한 걸 원해
Who will really love me truly
내게 기다림은 없어 I can't wait
더는 믿지 않아 now
I'm gonna make it mine
Love is a light I'll show my love is right
It's not a joke so give it to me right now
No more chance to you
You know
Hey d-d-d-dumb boy
꿈속에 매일 밤
Someone who will share this feeling
I'm a fool a fool for love a fool for love
I gave a second chance to Cupid
널 믿은 내가 정말 stupid
보여줄게 숨겨왔던 love is it real
Cupid is so dumb
I gave a second chance to Cupid
널 믿은 내가 정말 stupid
다시 한번 못 들은 척 기회를 줄게
Cupid is so dumb
