The Torn Emperor

The two were seated in the Emperor's discussion hall. It was clear that they refused to leave unless the Emperor settled the matter on the spot!

They were challenging to deal with, as both were dominant in handling matters; the Emperor did not know what to do with them. He could never upset Su Yaozheng as she was his biological sister who played an important role when he was competing for the throne. She even saved his life by blocking a sword from striking him. On the other hand, Su Yu was his youngest brother, and he watched him grow up, although they had different mothers. Su Yu had also protected him from poisonous wine and arrows when he had an intense conflict with his other brothers while also competing for the throne. 

To put it bluntly, he would not be seated on the throne had it not been for the two in front of him. He appreciated that none of these two had the intention to take over his throne. Therefore, he could never upset them, no matter what.
