The Ultimate Family: Xia Yu's Summer

Lin Xia: The heroine. A wealthy heiress with striking looks and a sharp mind, she gets into the same university as Xia Yu with excellent grades. She has no supernatural abilities, but can't resist a pretty face, male or female. She's a bit of a flirt, but never vulgar, mostly admiring people and saying exactly what's on her mind. She seems outgoing and cheerful, but deep down longs to be treated sincerely for who she is, not for her family background. She's direct and brave in love. Character arc: from an ordinary girl who is protected by others to someone who seeks power to protect her loved ones and become part of the family.

· Xia Yu: The male lead. A mundane human at first, he has Yehenara family blood and is the eldest son of the Xia family. He's highly intelligent, rational, and obsessed with money. His lack of supernatural abilities and complicated family background leave him feeling inferior and insecure; he longs for recognition and to be loved as someone truly irreplaceable. Lin Xia's flirtatiousness may initially unsettle him, but he's soon drawn to her frank sincerity and intelligence. He's extremely possessive.

· The Xia family: Xiong Ge, the Dead Man's Regiment Commander, Xia Tian, Xia Mei, Xiu, and others. They're key to Lin Xia's integration into the supernatural world of the Iron Dimension. They support her, provide comic relief, and have her back when trouble strikes.
