Lyrics (This Love):

(If time goes back)

(Memories will also be erased. )

I didn't tell you anything at that time.

I will let you know.

(What hurt you)

(makes you cry)

(to make up for your guilt)

(But I)

Can't live in a world without you

(You are all to me)

Time is like water to me.

I love you, thank you.

(Give me a warm hug)

I live because of your love.

(This is the power of love, right? )

(whatever you say)

(can't be wiped off)

(where the heart belongs)

My greed is good.

(thinking again)

I can't forget this heart for you.

(You know, I am)

Can't live in a world without you

(You are all to me)

Time is like water to me.

I love you, thank you.

(Give me a warm hug)

I live because of your love.

I can stand it again even if I go back in time.

(Those hard days)

As long as I see your steadfastness.

(My trembling lips)

(DuDu DuDu Lu)

(You know, this is me)

Can't live in a world without you

(You are all to me)

Time is like water to me.

I love you, thank you.

(Give me a warm hug)

I live because I love you.

I live because I love you.
