While romantic relationships can be fulfilling, nothing excites Yulia Nogah quite as much as financial gain. As the daughter of a marquiss, she was betrothed to Ramor Curion's son at an early age. Despite his rude personality, Yulia focused on the potential business opportunities that came with his title. Since she never had any emotional attachment to him, she wasn't bothered when he broke off their engagement to be with Julie Banache. It turns out that Miss Banache has delusions of grandeur and believes herself to be the protagonist in a popular novel where the main character is loved by many noblemen, including Ramor Curion and the prince of the country. She projects everyone in her life onto the characters from the book, with Yulia as the villainess, Ramor as the secondary male lead, and First Prince Rudonik Reino Palacio as Miss Banache's fated one. However, it's important to remember that fiction is just a story, and the person behind the publication of the book is actually Yulia herself. She has always been focused on expanding her businesses, and romance is simply another way for her to make money.
