The POV of a Supporting Character

In a story there's a heroine. And often the heroes are very rich, or very poor, beautiful / handsome, famous or they just really have a feature that you can feel they're the heroine. But me, I am not one of those I mentioned. I'm not rich but I'm not poor, my looks are average--plain. I am not too smart or clueless in everything. I'm just a normal high school student. That's why I knew that when someone transferred to our class, a very beautiful, perfect woman to our class, I'll just be a person in the background. And I was fine with that. But who would have thought that such a perfect girl would befriend an extra like me. Everything was going fine, I had the most perfect best friend in the world. But destiny is such a cruel thing. My only wish for 5 years will also be sought by my best friend. And what do I have to compete with her? Looks? Talent? Money? I can't compete with her. Because from the very beginning, she's the heroine and I'm just the supporting character.
