Y/n is the knight to Princess Catalina Ashbourne. Having protected her since they were teens, Y/n knows everything about her. When Catalina is returning from a different kingdom, the return journey goes awry. A storm hits, and while the carriage is making progress down a Rocky Mountain path, the weather wrenches it violently off course. Y/n rode Catalina’s unconscious body back to the Kingdom with one horse and a shattered knee. They both survive, but a month later when the Princess rouses from her coma? She doesn’t remember anything, and Y/n has to protect her mark that she’s known for years, but who doesn’t know her at all.
