I think the fact that he cares for her now he doesn’t want her to brush matters like that aside so trivially, or it could be that he thinks that it may mean she has bigger health implications and because he now cares for her he’s worried. Different things, I doubt it’s just one thing
He's slowly realizing that even though they have a really good relationship rn, there is a wall between them. An explicable wall due to their contract before. In the novel, the wall is acknowledged by both of them (and not really by the butler. Lol).
wait, why is he hurt? can someone explain?
