Marriage Of Convenience With Very Little Or No Spice

Okay, so I finished Marriage for One by Ella Maise a week ago and LOVED it so so much that I just can't get it out of my head. So I'm looking for more recommendations of similar marriage of convenience books that have no spice or just a teeny amount. Also nothing historical, please. Something set in the modern day with a well-developed FMC and sweet MMC. Thank you!
