Help!

I've been looking everywhere for this story. Read it years ago. Before 2014.

Quil/Claire , T or M, multichapter

What I remember:

-starts with Claire at 16, doing homework with a friend

-Quil comes with the pack and he always tries to help her because he wants to go to college with her

-Claire thinks he doesn't love her like she loves him

-Quil is hesitant about being in a relationship but does it anyway

-Embry likes Claires friend

-Quil and Claire are driving in front of Embry and Claire's friends car and they see Embrys car swerve a bit on the road and it turns out the friend kissed Embry

-Q/C have sex towards the end of the story- prom or some event happened?

That's all I can remember but it was so well written and one of my favorites. Any clue?
