Even though Feng Qian Shao wanted to help his younger brother, he was not in the position to do so. He knew very well that Feng Qian Bo was an easy going person and easily influenced by other people.
The only time in his life when he was acting so stubborn was when he first met with Lin Qiang and asked their father for her to be his wife. At that time, their father didn't agree and even wanted to kick Feng Qian Bo out of the family. If not for some persuasion from the other brothers, Feng Qian Bo might have been kicked out for real.
He ended up relenting and only made Lin Qiang as his concubine. Even though the status of Lin Qiang in reality would not lose against the main wife, no one tried to nitpick him.
At the very least, he still acted in the proper conduct outside.
Even though his wife couldn't be said to be happy, she still accepted this arrangement. The Feng Family was also powerful, making her unable to say anything.
Now that this happened.
