History
XL-49, an employee of the Library of Superman in the 30th Century, is sent back in time with super-powers which he has acquired from the science of his era. He travels in order to learn whether or not Superman and Lois Lane married. When he finds that they have not yet wed in the era in which he emerges, he takes on the secret identity of Futureman and tries to woo Lois in order to make Superman jealous and get him to propose to her. The plan doesn’t quite work out, but Lois is convinced that Superman secretly loves her.
Back in the distant future, XL-49 informs a colleague that although Superman has not yet married Lois Lane, he believes he has succeeded in putting the Man of Steel “on the path” toward matrimony.
