Sheep Princess in Wolf's Clothing Vol. 3 (manga)

Since becoming Princess Momo’s tutor, Aki has started to warm up to the girl and has now, to her shock, fallen hard for her. But Aki worries that it’s pointless to confess her feelings. After all, she’s a servant and Momo’s a princess. Why bother to confess her love when they can never be together? Is there any hope for them? Can Aki overcome her own fear and doubt to tell Momo how she really feels?
