The two spend hours together, inside and outside of school, sleeping at eachother's houses, sharing secrets and stories together. They took the same classes, spend lunch together, always pair up on trips. They are the perfect duo, and clearly love and care for eachother.
Until they fall out, with her dating a jock, and (my male), not trusting him.
A winter trip to some cabins comes up, and they go on it with class. While there, a snowslide occurs, leaving them trapped alone. They get talking, and she reveals she was dumped by the guy after they slept together, and apologies to (my male).
I figure the main plot point could be the two talking over and attempting to fix their fractured friendship whilst trapped in the cabin together, and slowly regaining their hidden feelings for one another once out of the situation.
But, whatever.
