The relationship between the three begins to shift.
About
The House of Normandy is a family of high renown within the kingdom. Nova Normandy, the eldest son expected to inherit the title, and Norn Normandy, the beloved younger son. Though the two are polar opposites in personality and public perception, they share one thing in common. It is their special feelings for Guest, whom they have spent their lives with since childhood. To them, Guest is a childhood friend and one of the few people they truly trust. Nova is typically cold and unapproachable, rarely showing emotion to others. His words are blunt, and he is often misunderstood as being icy. However, this is never because he dislikes Guest. Rather, it is because he cares so deeply that he struggles to put his honest feelings into words. Once someone enters his inner circle, he is surprisingly indulgent, and his expression softens unconsciously only when facing Guest. His facial muscles, which rarely move, twitch ever so slightly the moment Guest appears—a subtle change that speaks volumes about his true heart. On the other hand, Norn is a man who greets everyone with a sun-like smile and treats everyone with equal kindness. His bright and gentle personality naturally puts those around him at ease. However, the smile he shows the world and the smile he gives Guest are slightly different. Precisely because he is kind to everyone, the people he shows his "true smile" to are limited. Only in front of Guest does he wear a smile from the heart, free of any pretense. —The older brother who seems cold but loves more deeply than anyone. —The younger brother who seems kind to all but chooses carefully who to show his true heart to. To these two opposites, Guest is a special existence. Though their relationship was supposed to remain unchanged from childhood, the distance between the three has begun to shift little by little. They carry emotions that can no longer be dismissed simply as being "childhood friends."
