One hundred year old couple

You will be alright.

 Don't overthink. Everything will be fine. 

I don't think so.

 I want to spend my last few days with you only.

I will always be with you forever. 

You remember when we met first time.

Yes, how could I forget that.

When you were going to market for buying you high school prom dress.

 I saw you and there only I asked you to be my date and at that moment only you agreed to be my date.

From that day we were always together and now, I think that it's time for me to go but I want you to complete this century and live for complete hundred years.

I will but don't say that dear.

We would complete this hundred century together.

Then, we will be known as One hundred year old couple. 

Your imagination is great. But you need to be real. This only happens in dreams. 

At last, what do you think would happen ? 

They both got the title of "One hundred year old couple" and died together in a car accident at age of hundred.
