From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): Nanase Karina is an oddly cynical, sexually precocious 10-year-old girl, who has an unusual romantic relationship with her older, 12-year-old cousin, Tsukamoto Kouichi. Another classmate, Watanabe Kiichi, has a desperate crush on Karina, but he knows he can't compete with Kouichi, who has top grades, is the student council president, and much more. In their school life, Karina and Kouichi approach situations in a way that shows that they don't have the innocence commonly associated with children. For example, when Karina becomes the next targeted conquest of the school's playboy, she plans to beat him at his own game. [tethysdust]

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. What exactly is Nate’s true intention? And is escaping his grasp really what her heart desires?
