Arende was formerly friends with Roen Lamoa and Rassius Luine, a relationship that has lasted until adulthood, though her mother, the Queen, was rumored to have been guilty of Ras's mother's suicide. While Arende grew up as a princess, Roen and Ras were recruits in the Royal Army and soon rose to higher ranks. Over time, Arende developed romantic feelings for Ras, which he did not reciprocate, but he did appreciate her company as a friend. In letters, he talked with her about his problems, worries, and plans. Roen, on the other hand, developed romantic feelings for Arende, though he does not realize she is aware of the infatuation. However, like with Ras, Arende appreciates Roen's presence and above all his caring nature when it comes to her safety, even if he is overzealous at times.
