Please Come Back At The End of Time.

I just want to take care of you
But everything i do is wrong
I didn't want to make you cry, i never meant to make you cry
Oh, i tried
Cath, please come back to me
I know that i am wrong
I just can't understand a single thing you say
And even if i try, i'll never be as good
And even if i'm sorry, i will always hurt you some way, some way
I just don't understand what i did wrong
So, i am sorry, my bro
