In that case let me respectfully yet vociferously disagree with the majority of voices in this thread. Shallan and Kaladin don't know each other. They have a confusing connection due to a single day of intense stress and shared secrets. That isn't a relationship, romantic or otherwise. So many comments here talk about their story fizzling or not going anywhere. That's because there was no story. There was three years of fans obsessing over what might happen.
Adolin and Shallan have had days, weeks, and months in each other's company. They have had huge amounts of time and interaction that we don't see because it wasn't explicitly written. They have a real relationship.
Yes, Shallan sometimes gets caught up in Kaladin's wake. As near as I can figure everyone gets caught up in Kaladin's wake (except perhaps the Kholin women). Literally every character in the series who has met Kaladin has been greatly affected in one way or another. At no point did I ever take "Shaladin" seriously, and I am more than a little surprised that so many people did/do.
