Let Bygones be bygones

It's not easy for me, to say that thing
It's not easy for me, to know the truth
It's not easy for me, to know that thing
It's not easy for me, to hear the story

I'm afraid it will hurting you
I'm afraid that i shouldn't say that thing
I'm afraid that i'm not ready to know
I'm afraid,i'm afraid

I promise, i'll let bygones be bygones

Cause I .......

The book that i gave,
The things that I've done,
The attention that i gave,

It's all have a reason,
It's all because of something,
I do because of something,

I can't tell you what,
I can't tell you why,
I just can do,

I hope you understand the reason,
I hope you can read the answer,
I hope you know the cause,

I will tell you why,
When that time has come.
