《I won't give up》的詞曲由蔡健雅完成，中英文歌詞如下：
中文版：
我明白
感情不是必然
你也不再 是我的例外
你離開
我明白
我的任性不該
成為你
放棄我們的阻礙
我知道
愛總有遺憾
但是我不怕痛
只要你給我一個理由
也許
你不曾明白我的認真對待
但是我相信時間會證明我現在所做的一切
我不管時間流逝多少歲月
對你的愛
我從沒後悔
我不放棄愛的機會
只要你能給我個理由
我不管路途多少曲折坎坷
只要你能給我個理由
我不放棄愛的機會
我不放棄愛你的機會
英文版：
I won't give up, no matter what they say
I'll keep on going, even if it all falls apart
I won't give up, no matter what they say
I'll keep on going, as long as I have you by my side.
I understand, that love isn't always easy
And you're not my exception anymore, I know it
But I'm not afraid of pain, as long as you give me a reason
Maybe you don't understand how serious I am about this
But I believe that time will show you everything I've done for us
No matter how time passes, I won't give up on us.
I don't care how fast time flies, I won't give up on you
I'll keep on going, as long as you're by my side.
I don't care how many obstacles stand in our way, I won't give up on you.
I'll keep on going, as long as you give me a reason.
I don't care how many challenges there are ahead, I won't give up on you.
I won't give up on loving you.
