All Roads Lead to This. Leads to This, #1

Cedric and Rueben have been best friends since sixth grade, and cannot imagine life without each other - Cedric was there for Rueben when he came out to his family, and Rueben was there for Cedric through every step of his transition.  Now, both twenty-four and working at the same plant shop, their boss gets an opportunity to receive some extremely rare plants she's wanted for years, except there's a problem: the plants need to be collected in person from across the country, and she cannot make the journey herself.
Rueben, ever helpful, is quick to volunteer him and Cedric to travel across the country in her place.  Cedric is apprehensive about the trip, both because he hates sudden changes to his routine, and because he may or may not have a few secrets he hasn't told Rueben about. Secrets like the fact that he might be in love with his best friend... All Roads Lead to This is a low angst HEA m/m romance that involves a road trip across South Africa, sharing a bed, heavy pinning, and childhood friends to lovers tropes.
