Han Xiaowan had purposely said 'Xiaowan' in a softer tone, hoping to get closer with Fu Qinglun and Huo Beichen. She did it in a subtle way to try to appeal to the two successors without alerting Su Zhe.
The Han's had actually been rich and influential in Karghalik in the past. However, due to Han Dong's poor management skills, they had gone downhill and Han Xiaowan could only wish to marry into a rich family to become a respected young madam. If she was able to succeed this way, she would be able to lead a good life in the high society and become a part of those social circles.
