I think this is the first time when I read about a secret couple that doesn't have jealousy, wanting others to know about their relationship, problems with third parties wanting to get together with one of the secret couple.
The problems were about not knowing if their feelings were mutual.
I liked their relationship they were truly like the title: Partners , Friends, and Sometimes Lovers and they were happy like that
