My Silent Fiance is a Knight with a Beautiful Voice: Love at First Listen

Katina, a baroness, was born with a good ear. She is especially sensitive to people's voices, and once she hears someone's voice, she never forgets it and can distinguish it accurately. Although her good hearing sometimes caused her problems, Katina quietly and quietly studied hard and was chosen to be the princess's personal attendant because of her excellent grades. Thanks to this, she was not very good at socializing, and compared to her beautiful older sister, she was a plain and unobtrusive younger sister. On the other hand, her fiancé, who was chosen while she was still in school, is the son of a count and the princess's guardian knight. He has a face so beautiful that women envy him, and although he is a diligent and talented knight, he is a very quiet man. It has been half a year since their engagement, and although she has never spoken to him, the first time she heard his voice, it was irresistible to Katina! Source: MU
