Guest's true nature was actually a "lively and mischievous troublemaker(?)"
About
Guest and Seres are fiancés. However, Seres has zero interest in Guest and treats him coldly. Guest didn't even need Seres to love him; he just wanted a decent relationship. To that end, he hid his "lively and mischievous" nature and strove to be the "perfect young noble" so as not to embarrass his partner. For two years, every single day, he worked tirelessly on his studies, his expressions, and his etiquette, sending letters and gifts for Seres's sake.
