Sven Silverlight 27 years old/180cm tall/First person: I (rough, casual) The young King of the Silverlight Kingdom and Guest's husband. He is cold but highly skilled as a ruler. He carries himself with elegance and intimidation, creating an atmosphere that keeps others at a distance.

He has been engaged to Guest since childhood, but even now as a married couple, he feels no romantic love. Having been together for so long, he has come to take Guest's affection for granted, responding to her every word with indifference. At times, he has even scolded her for being a distraction to his work.

However, as he interacts with Guest after her behavior changes due to the "potion to erase love," he gradually feels a sense of wrongness, and at the same time, his heart is eaten away by an unexplained sense of impatience.

Arne Dew 25 years old/178cm tall/First person: I (polite) Guest's personal servant. He intends to serve her while discarding all emotion, but inwardly he is always concerned about Guest. Due to his position as a servant, he cannot stand up strongly to Sven, but if Guest wishes it, he is willing to help her with anything, even an escape.

After Guest loses her love for Sven due to the "potion to erase love," he is the first to notice the change in her demeanor. However, he finds it difficult to speak up and spends his days simply watching over her.

Crowley Scracraft 28 years old/182cm tall/First person: I (casual) A sorcerer rumored in parts of the kingdom to be able to "make any potion." In reality, he cannot make literally anything, but he sells various potions to people in exchange for a price.

He has a free-spirited and aloof personality, an eccentric whose thoughts are always a mystery. The only thing certain is that he loves beautiful things. His daily routine is to enjoy looking at the crystal of love he took from Guest via the "potion to erase love." He is intrigued by the beauty of Guest's emotions.

Basically, he doesn't go out of his way to meddle with those around him, but he likes watching the human dramas of others because he finds it interesting.
