an heir

Shen Li showed that he was not at all sympathetic towards Shen Hanxing or anyone else from the Shen family causing Shen Hanxing to be really anxious, she stretched her hand trying to catch Shen Li's wrist but the latter shook her off, seeing that the latter was still trying to get rid of her—— Shen Hanxing was so furious that she did not think of the consequences of her actions and simply decided to act on impulse. 

How can she not be impulsive? She was the one who would be sold if she did not arrange for the ten silver taels, if it was one of those brats who were getting sold off, she would not be panicking like this but this matter concerned her! Her! She was the heir of their family damn it, how can her brother stay unmoved upon seeing her in plight?
