Story
Countess Yuffie has a big problem: her so-called "older brother" Nate. He's brilliant, handsome, and talented in everything—but he's not human. With black wings and a mysterious aura, Nate is a supernatural being who once saved Yuffie as a child and then somehow claimed the role of her older brother. As she grows older and dreams of finding love, Yuffie’s every attempt at courtship is sabotaged by Nate's fierce protectiveness and suffocating affection. Despite her determination to break free from his grip, she finds herself blushing at his every over-the-top gesture.
