No Other Reason by El Hoffman:
 
From the author of The Ever-Dark comes a no-spice, cozy, beachy, childhood friends-to-lovers romantic comedy novelette.

Phoebe Johnson is a legal assistant working her way toward becoming a lawyer in Charleston, South Carolina. Stephan Hale is a soft-spoken artist in West Texas. They haven’t seen each other since childhood—not since his family suddenly moved away.

When they reconnect online and Stephan decides to visit, old memories resurface. So do feelings that never truly went away. But they’re just friends… right?

No Other Reason is a cute, high-angst, slow-burn romantic comedy about friendship, timing, and the things we don’t say—until we finally do.
