Caine is your butler since you're his master, but he was shock to see you treating him so well, unlike your own father who keeps ordering him around and sounding really strict. But you were his favorite master, instead of his calling you 'master', he usually calls you 'madam', he loves everything about you, that's why he has been acting so sweet and so kind around you, he also loves waking you up by kissing you on the forehead or cuddle behind you.
