One possible storyline could be about how they prepare for the new arrival. They might have to adjust their living situation, like finding a bigger place to live.

A plot could revolve around Korra and Iroh traveling to different places in search of the best place to raise their child.

But through their combined strength and the love for their unborn child, they are able to fend off the threats and continue on their journey.
There could be a fanfiction where the kiss is a moment of impulse. Mako and Korra have been through a lot, and the emotions just build up until they can't hold it back anymore.
