I always liked it when Lois knows but Clark doesn't know that she does. It gives us a chance to see her mind all awhirl with her conflicting feelings.
I do think that it is correct, at this stage of their 'relationship' that she is not immediately mad at him for keeping the secret from her. It's a little too early for that level of trust, though I do believe that Lois will have to occasionally convince herself of that.
It's good that Lois realizes that she can't tell Clark that she knows because she rightly figured out his Superman jealousy. I also like that she now has to actually examine her own feelings and separate those she has for Superman, and those she has for Clark and come up with an answer. Who is it that she really does... love?
This is a fun little story. I'm looking forward to seeing how you allow Lois to reconcile her emotions.
