Tragic Irony - Carlos Pereira Cen

Here is the little and complex history of a friend of mine...
He met a girl a month ago and liked her, they went out one single time... after that, he didn't knew what to do. She was very tender with him, but he wasn't sure if she liked him.
He decided to approach the girl's friend.
A girl that was also cute. Well that was his first impression...
He thought: "maybe she can help me with that girl..."
But suddenly he fell in love with this girl... and so the girl with him...
The problem here is that... she has a boyfriend.
They love each other but they don't know what to do...
