This story is just perfect! And the high school setting is something that most of us can still relate to, even if it's been years . . . or decades . . . since we were in school.
I was surprised to see all the previous FDK where people were concerned about Clark falling for a student, and I noticed that you made it clear in this chapter what his thoughts were on that. But I was never worried. For one thing, you can be attracted to someone who's underage, but being attracted to someone doesn't necessarily mean falling into a sexual relationship. Clark isn't the predator type, or he wouldn't be Clark, and the story really wouldn't belong on these boards. So even if he fell for a student, he would wait until she was of legal age before he tried to take the relationship past friendship. And if he's anything like the Clark in the series, he'd give her plenty of time to make sure she was comfortable in the relationship and then he'd still wait until their wedding night for anything to happen. But he can move into a romantic relationship more quickly here, once he finds out Lois's true age.
One thing did seem out of place to me--I think Clark said he'd introduce Lois "real quick" and I think an English teacher would have said "real quickly." But I apologize for criticizing ANYTHING because I have so much admiration for your writing ability! I really can't wait to read the next chapter--please don't make us wait too long!
