A crying boy

A boy badly wanted to cry,
But he didn't, because he was a guy.

After some times, tears did came,
But now, he was playing game.

But it was not water, it was blood,
His room was filled, like a flood.

There laid a body, with a lot of tear,
He did something that no one was aware.

There was a book whose pages turned red,
Congratulations everyone, he was dead.
