Her eyes widened in fear. Assassination? That's something she feared after being reincarnated as a noble. Assassinations were common at the royalties and the wealthy people of the empire, but it was no doubt that someone has harboring ill feelings towards a member of the royal family. She assumed that the king was the target, which is true after Noah spilled the details.
"So what do we do now? They're probably had devised a plan."
According to the novel, there was a murder attempt to the king but it was after the victory of Noah. They will put the blame towards the duke, provoking the commoners to start a rebellion towards the royal family. It was successful at first, but Beatrice had gathered enough information to prove Noah's innocence. Without her, Noah would probably be living branded under the name of a murderer. That might be touching, but that was no use for the current situation. The flow of the story was disrupted once more, causing several changes to the characters and sequences.
Additionally, the king was nearly killed due to a stab on his heart. He fled from the palace to regain his strength. His disappearance caused a disruption in the royal family, that led Noah to be lashed out of his title. After proving his innocence, he decided to stay away from the palace.
"I already have one. But I need your help." His eyes were more serious. The life of his brother was on the line, one mistake and it will end up as big disaster. He held her hands, to Raeliana's surprise. Gripping her fingers, Noah instructed her to guard the king's quarters. They prepared a set of maid's uniform so that she could be in disguise. Noah reminded her to be attentive of her surroundings, be alert once she sensed something suspicious.
The reason why Noah had asked Raeliana to guard the king's quarters because he assumed that the mastermind was staying at the palace. They will surely know the faces as they had seen them around. Raeliana was only the fresh face here, so he used this to fight against the underhanded tactics of the murderer.
She wasn't agree of the duke's preposition, but it's her chance to prove her true self. Not that she can only save the king, she could clean her tarnished name. Two birds in one stone! Raeliana has some troubles of wearing the maid's uniform that slightly angered the duke.
"Please be quickly next time. Anyways, you should go now. Don't forget to nudge the vase so I can alert the knights. Are we clear on that?"
She nodded her answer. "Be safe, sir duke."
"Think your safety first. I will be leaving now."
