Braxton's and Summer's are rivals?

Not too long after that, their first young master was killed and the second young master is given the throne.

…..

  At first these four families and their rivalry use to cause a havoc and council use to control it. 

After the destruction of two families out of this four, council almost thought they won the peace they wanted. 

However Sophia got killed along with their other two leaders in that exact time. This weakened the council and these two families again started and continued their rivalry and undying revenge. 

At last, the first young master succeeded in winning against Michaelson's and they thought it will leave them in peace. 

However council which is boiling with the rage due to their loss started attacking the last family which is in power. At least that is what others know….

In middle of all this mess the current king of them, the first young master was killed.
