Probably a bit of a long shot in the dark. But I'll give it a go.
Racheli's best friend is a guy named M. He's happily dating a guy named B. The guys have been dating for a good 4 years and they all consider each other family.
But then B is cheating on M and he's heart broken. Of course, Racheli tries to comfort him. They are crying together, watching movies and eating icecream and agree how much men suck. M stays the night and in the morning before he leaves he suddenly kisses Racheli. She tries to shrug it off since she knows they are friends and he's emotional. M. always thought he was gay but suddenly he has those feelings for a girl. She is kind of shocked because she always had feelings for him. But she had done the smart thing to hide them. She is also scared to lose him of course.
I would love to find a writer to write M. I dont really want to bring in B. or turn this into a cheating line. I would rather like to focus on his confusion and the fact he's torn. It's less about the sex but more about the two of them finding together, maybe.
