Mafia Prince

Qi Yuze placed the box on the kitchen counter and went back to his study. Out of sight, out of mind was the strategy. He didn't even understand why he was feeling so irritated right now. Was it because she said that he had a suspicious nature? But she wasn't wrong either, he naturally was suspicious and she was also right that his family dynamic forced him to develop this suspicious nature.

Then what was he mad about right now? Why didn't he like her words? Was it because she called him the Mafia Prince? But in a sense, that wasn't wrong either. He did belong to the Mafia family. 

Did he not like the fact that she knew about his family background? Or was it because every single word of hers hit a home run?
