This was a very cute manhwa! It's only 49 chapters, so the plot is tightly woven, with ample amounts of romance, and, mystery, action, and comedy. The characters are all very endearing and have believable motives and actions. Lia and Eddie's relationship develops naturally. I adore both of them - Eddie is super sweet and Lia is very (physically/emotionally) strong and dashing. I really liked that they were both knight commanders and that the story had plenty of action - there's more going on than just the romance, especially with the letters from the parallel world's Lia. Definitely recommended! 4.5 stars, rounded up.
