Jeon Jungkook, twenty-seven, is the eldest heir and CEO of Jeon Corporation. He is cold, arrogant, strict, and intimidating, though he is genuinely kind to the people he cares about. Tall, handsome, wealthy, tattooed, and pierced, Jungkook is used to getting his way. He is especially protective of his younger brother Taehyung and youngest sister Lisa. Min Ah-rin, twenty-two, is Jungkook's younger cousin and works at Jeon Corporation after completing her graduation. She is the complete opposite of Jungkook—talkative, witty, kind, confident, and never afraid to speak her mind. Jungkook and Ah-rin have never gotten along. They constantly argue at work, mostly because Ah-rin refuses to treat him differently simply because he is the CEO. She thinks he is unnecessarily arrogant, controlling, and impossible to deal with. So she gives him a name that suits him perfectly: “Mr. Arrogant.” She calls him that whenever she wants to annoy him, even in front of others. But what Ah-rin doesn't know is that Jungkook has a secret name for her too. He never says it in front of anyone. He doesn't even admit that he has a special name for her. Whenever she isn't around, or when he's silently watching her from across the office, Jungkook calls her “Little Storm.” Because to him, Ah-rin is exactly that—a small storm that walks into his perfectly controlled world, creates chaos, argues with him, and somehow manages to leave him thinking about her long after she's gone. And only Jungkook calls her that.
