|“||I can't trust anyone... Ever since I was born, people have tried to delete me to steal my throne. My siblings, relatives, close associates... They devised all sorts of plans to erase me. Actually, I had a few close calls in my life... I would think I had faithful followers, but they turn out to be the same as everyone else. If I can't trust the ones most "loyal" to me, How can I trust complete strangers? The only thing I trusted about strangers was that they were out to betray me. I thought that I shouldn't bother trusting others to begin with if they were going to betray me in the end. Not trusting others... It's made my whole life nothing but loneliness.||„|
