Lyric discussion by Ballantyne 

In fact, I completely agree with beautifulnobody, and according to that intepretation, I think the story goes like this:

They knew each other but they never really talked to each other; she was in love with him and started the flirting, and he knew about her feelings but he wasn't interested. Unsuccessful, she started to getting depressed and she could only think of "If I could look you in the eyes...I couldn't let you go".

One day, he found her body and called an ambulance. And he was blaming himself by being the cause of her death. Later then, he apologized to her parents, they responded that he didn't have to apologize, it wasn't his fault.

And that's it. It's about unrequited love.
