Bai Ruozhu also secretly blamed herself for being too careless; in fact, she should have been more suspicious of Qin Kaichang. How did it just so happen that he was always the one to deliver goods to the Hot Spring Mansion? How was it that he constantly managed to meet Guizhi? And how coincidental was it that she encountered him begging for food in Jiuzi City?
Just like her second brother said, Qin Kaichang's pursuit of Guizhi, how could he not mention it to her brother? Pursuing a friend's sister but not sharing any information with the friend, wasn't that a bit strange?
Moreover, Qin Kaichang had always been around them; he must have been able to gather a lot of information, right?
Still, she was quite certain that when she found Qin Kaichang, he really had a head injury unless someone else with superior medical skills to hers had treated him with medicine in advance, concealing any signs from her.
