Bring sister back and live with her

Qian Lai was scared by her father's loud roar. It was not that she was not trying hard enough. It was because her father did not give her a chance to rest, the night before the competition he forced her to stay awake till the morning and only let her sleep a few hours before waking her up at dawn. 

He told her that learning in the morning would help her remember the content better. Qian Lai did remember the content but she was too tired to even write the content properly which caused her marks to be lowered. Qian Lai tried to explain the matter to her father but he was so angry that he did not hear a thing that she said and only felt like she was blaming him which led to another round of scolding.
