YOUR HYUNJIN castle

Hyunjin is a commoner. Meanwhile, Minho is party of the Royal Family, the prince. One day, Hyunjin got caught disrespecting the king and queen, so they took him to jail. Only for saying 'stupid', which offended them. But... Hyunjin had escaped. Where is he? He's in Minho's room, hiding as Minho is about to snitch.
