Happy New Year, KK! I love this ending to your vignette series. I was wondering if it would come in the vise of a POV from Perry, or Jimmy, or Jonathan, after your last one.
One of the things I like most about L&C is that Clark doesn't act like 98% of most men on TV, i.e. always trying to get into a woman's pants. He's about love and romance. You demonstrate that here. Lois is trying to get romance the pants off him and all (perhaps 'all' isn't quite the right word, since Lois does persuade him after all), while his mind is set on proposing.

I'm glad that both agree that New Year's is a good time to create a memory worth keeping.
Quite the cute story.
Clark, it's probably best if Grammy Kent's (Grammy Clarke's?) ring stays out of view for tonight. The last thing you want to think about during your first time is your grandmother, even inadvertently.
PS: I never noticed Clark not saying the words "I love you" to Lois. He certainly showed it, which is more than those 98% I mentioned above. Lois certainly didn't doubt his regard for her, and even mentioned seeing it in his eyes. Her actions have proved to him that despite the lack of words, his sentiment was clear.
