After the loss of her mother, Zarah goes to visit her aunt, whom she hasn’t seen since she was a young child, but she is greeted instead by a young man named Stein, who introduces himself as her aunt’s son. He seems aggressive from the start, his cold smile no comfort. It turns out that Zarah’s aunt has passed away and left her a huge inheritance. Though it’s a complete surprise to her, Stein believes Zarah is nothing more than a gold digger. Her intention had only been to uncover the mystery of her birth, but the condition of the inheritance states that she must live in her aunt’s house for six months before she can claim her legacy. Will she be able to handle red-hot Stein’s icy attitude until then?
