I love this song! They are friends for a long time. But the girl secretly loved the guy. She tried to pretend & listen to the guy whatever he shares, his ups & downs - even his lovelife; logically, it's painful for girl. But because they are friends, even if she feels sad, she's still glad to be a friend of the guy! Ouch! This is what I'm going through with. - a Friend of Mine. :)
