Wei De always felt that Song Yin progressed so quickly and achieved what he had once set for himself not because he was mentored by Qiao Nan. It was purely because he was in Zhai Sheng's team and thus had higher chances and probability to gain credit. That was the reason that he was promoted so quickly.
Hence, if he was the one who followed by Zhai Sheng's side, he, and not that lousy Song Yin, would be the one becoming the deputy company commander today!
Having said so much, Qiao Nan was a troublemaker, and Zhai Hua was not true enough to him. She did not love him that much.
As the only daughter of the Zhai family, if Zhai Hua had deployed all tricks and means such as crying, kicking up a fuss, and even threatening to commit suicide, he could become the company commander too!
