This story is presented as an Untold Tale of Superman.

Synopsis:
Clark Kent recalls a time earlier in his career as Superman when Lois Lane did not suspect him of being the Man of Steel. Lois had seen Superman disappear inside the Daily Planet building and suspected that he might work there in his secret identity. However, she was so convinced by Clark’s meekness, she never suspected Clark.

Clark goes through a lot of trouble to protect his secret, but Lois pays no attention to him at all, while she tests the other employees of the Planet. Lois catches Clark changing into his Superman outfit, but she believes he is only playing a joke on her. Later, it occurs to her that his shyness is a deliberate pose. She begins to test Clark, who is able to protect his secret. However, Lois’s suspicions have been aroused, and she continues to wonder.
