My newest one. I can't decide the title.

I'm watching you in Happiness.
You brought smile to my face.
But that will end soon.
As you go out with someone else.

When you smile at someone
Then I breaking down in tears
When you hold somone's hand
The sky fall down onto my head

Why do you hurt me like this?
Don't you realize the love that I get for you?
Is it hard for you to know my feelings?
Or you didn't even care with this kind of love?
