I suspect you understood.

I cannot unveil this one truth.

No! I actually can, but I will not.

Not revealing my feelings gives me a chance.

A chance of not being heartbroken

So I hide them.

Then it will never hurt.

It’s not I am afraid to face her.

But express is to reveal.

and I am sure she will not feel the same.

So I will let my feelings be.

Although I know what it means

Not trying means failure.

But like a coin.

Trying can also mean either failure or success.

Either way. 

I am afraid to reveal.
