In this elseworlds story. Clark first met Lois when Clark's co-workers played a joke on them both, setting them on a blind date. The two got irritated over the joke, but found themselves falling in love.
After a few months, Clark told Lois that he is Superman. They got married, got a house near the beach, and had two daughters. Carol and Jane Kent. Eventually she (and Clark) found out that they daughters had developed superpowers, and become superheroes. They were pretty much fine with that.
Lois lived happily ever after with her family.
