Once Your Maid, Always Your Shield - Episode 10

Grandpa appoints Hailey to teach three children and accompany them to the elite school to fix the household's bad atmosphere. On the first day Hailey is to guide Natalie, but Natalie arrives without the required uniform or badge. Wealthy classmates mock her, calling her a 'bumpkin,' and one vows to block her entry. At the gate someone exposes that Natalie's uniform was thrown away to humiliate her and confronts the saboteur: 'You threw away her uniform... So I won't show any mercy.' The episode ends with the sabotage exposed and Natalie's admission left unresolved.
