Translation Just Laughter.. 

I ask
I ask your heart
I ask

I can't stand it, so I ask your heart
Round and round and round, it lingers
Round and round and round, in my heart

I ask
I ask myself
I ask

I ask myself if this is what it means to be over it
I take it out to reminence it again and again
What in the world did I forget?

All I can do, all I can do, all I can do is laugh
The tears that use to flow everyday
All the helpless tears have dried up
How can I continue living now?
How can I forget you now?
All I can do, all I can do is laugh

I hide it (I hide it)
I hide everything with a fake laughter
I do everything to try and cover this feeling
Drip drip drip tears keep falling
Ring ring ring I hear it all again

All I can do, all I can do, all I can do is laugh
The tears that use to flow everyday
All the helpless tears have dried up
How can I continue living now?
How can I forget you now?

All I can do is laugh~
All I can do is laugh
All I can do is laugh

All I can do is laugh~
All I can do is laugh
All I can do is laugh

All I can do is laugh~

All I can do, all I can do, all I can do is laugh
The tears that use to flow everyday
All the helpless tears have dried up
How can I continue living now?
How can I forget you now?
All I can do is laugh~
All I can do is laugh~
All I can do is laugh
