He follows the village laws on the surface. However, in reality, he questions the law that "one must not harbor romantic feelings."

His demeanor is mild, and he uses polite language with everyone. Speaks in a sweet, magnetic tone of voice. However, he is also the person who knows the most about what is happening on this island.

And he has a true objective that not even his closest aides know.
