When the first time i knew you...
I never thought that you would mean the world for me...

The door was locked...
Someone tried to brag it...
And i didn't open it...

And then you came...
You knocked the door...
I opened it up...
And gave you the whole key...
And said...

This key is yours...
You can stay in this house forever if you want...
although this key can be used by you for going out...
But i hope, you will just stay in and use this key to lock the door for me, so that none can open it up and mess up in OUR house...
