Honestly I would love to find out more about Ray and Monica and well maybe how they met Emma and how things came to be more or less. And definitely more of a switch up between Hals POV and Emma's POV. As for the plot, well maybe a slight misunderstanding that gets resolved quickly or maybe a little jealously, like for example Emma was annoyed by Becca, so maybe someone tries to flirt with Emma now that she is taken and well thus more "interesting" and "desirable" (some people are weird like that), so they try to see how stable her and Hals relationship is. In the end everything is good ofc and their bond gets stronger. Maybe you guys can work with that :)
