[MrTerrorist]

Spoiler for c64:

Yue's father reveals because of the succession crisis between the brothers, the nobles began fighting each other for power and were lying to Yue about what was really happening in the empire so they could raise their ranks and he blames everything on Yue for being naive and not totally controlling everything. Yue refuses to believe what his father said including that his Prime Minister has been hiding the infighting so he can get more money but the old emperor actually succeeded of casting doubt into Yue's mind. Soon Yue start to slowly distrust everyone to the point that the Long family starts a rebellion and attacks the capital.
Yue watches the battle, asking his PM that if everything was his fault for being the Emperor only to be stabbed by him.
