King's Maker: Who are you?

Please no watching this if you don't want spoilers. This is heavily for the last chapter. Heard this song, and it made me think TOO much of the "what if"s for the series. WHAT IF: the crown corrupts our king and he is exactly what he got rid of. Shin is watching from his side, first it's a small thing like ignoring friends - then a new rule is decreed that benefits no one but the royal family - what if he goes corrupt, and instead the other princes must save the kingdom?
