It appears that a lot of people attempted to take her life and she was sure they would continue to do so. That's why she already asked Mr. Mo to have more bodyguards assigned to her so that they can have more shifts as they are preventing a lot of accidents.
The guards of her father who wasn't assigned to continue looking for him were also reassigned to continue working for her. At least her bodyguards can have more rest as their jobs are very tiring.
The bodyguards under Mr. Mo and Lorna were able to have their shifts and at least can rest but Mr. Mo and Lorna were still doing a full time job. Their pay is of course higher but their job is also more tiring compared to others.
She already asked Mr. Mo if he wanted to have a time off but he rejected her offer. Mr. Mo said that he was already very good and didn't need any more time to rest. He said that the four hour rest for him to sleep is already enough.
