Derick and Lily are sitting alone in the park one night.

Derick:
I guess we are the left overs in this world

Lily:
I think so .. all of my friends have boyfriends
and we are the only the 2 people left in this world
without any special person in our lives

Derick:
Yup, I don't know what to do

Lily:
I know! We'll play a game

Derick:
What game?

Lily:
I'll be your girlfriend for 30 days
and you will be my boyfriend

Derick:
That's a great plan,
in fact i don't have anything to do
much for the following few weeks

DAY 1:
They watch their first movie
and they both are touched by the romantic film

DAY 4:
They went go to the beach and have a picnic
Derick and Lily have their quality time together

DAY 12:
Derick invited Lily to a circus
and they ride through a Horror House
Lily was scared and she thought she touched Derick's hand
but she actually touched someone else's hand
they both laughed

DAY 15:
They saw a fortune teller down the road,
and they asked for their future advice.
The fortune teller said:
"My darlings, please don't waste the time of your life.
spend the rest of your time together, happily."
Then tears flow out from the teller's eyes

DAY 20:
Lily invited Derick to go to the hill
and they saw a meteor
Lily mumbled something

DAY 28:
They sat on the bus, and because of a bumpy road
Lily gave her first kiss to Derick by accident

DAY 29:
11:37 pm:
Lily and Derick sat in the park where they
first decided to play this game

Derick:
I'm tired Lily...Do you want anything to drink?
I'll buy you one.. I'll just go down the road

Lily:
An Apple Juice, that's all thank you

Derick:
Wait for me

20 mins later
A stranger approached Lily

Stranger:
Are you a friend of Derick?

Lily:
Yes, why? What happened?

Stranger:
A reckless drunk driver ran over Derick,
he is in critical condition in the hospital

11:57 pm
The doctor walked out of the emergency room
he handed Lily an apple juice and a letter

Doctor:
We found this in Derick's pocket

Lily reads the letter and it says:
Lily, These past few weeks,
I realized you are a really cute girl,
and I am really falling for you
Your cherished smile, your everything,
when we played this game
Before this game would end
I would like you to be my girlfriend for the rest of my life
I love you Lily

Lily crumpled up the paper and shouted:
"Derick! I don't want you to die
I love you .. Remember that night when we saw a meteor
I mumbled something
I mumbled that I wish we would be together forever
and that we would never have to end this game.
Please don't leave me Derick .. I love you!
You can't do this to me!"

Then the clock strikes 12 ..

Derick's heart stoped pumping..

It was the 30th day
