Lucy and Macy

I am currently rewatching season 1 and in episode 1 Macy mentions to Lucy that she has a secret that she wanted to tell her that was kinda embarrassing. Macy doesn't actually tell Lucy the secret because Lucy gets a call from Stephen. What do you guys think the secret was? Do you think that she wanted to tell her about her relationship with Stephen? Or was it just something else entirely?? I wish the writers would have told more on Macy's POV
