Ah, I remember this one. I feel really bad for the protagonist of this.
I mean, if I were him, not only would I have just lost my shot at my first love while learning he'd had a (quite precious) lover the whole time, I'd also have just learned I'm stuck as an outsider to there suddenly being magic in the world.
I would be anguished, I would be in conniptions. What a brutal gouging, to tell you that you're not the protagonist of your own life, and have been left out from all the good parts.
