When everyone at the Heavenly Palace finished breakfast, they went to do their activities. As Carolina only had to go to the laboratory to study and perfect her alchemy, she preferred to take the breakfast of those who were not up yet before doing that.
It was not that she wanted to be a good sister and wife, but that it was already quite late and she could not let them continue sleeping. To be more specific, Candice was the one who could not stay in bed, as she had to go to her store to attend to business matters.
If it were another time, Carolina would not worry, but currently, she could not afford that luxury. Candice's business was the commercialization of food, so, in this time of conflict and chaos, it would have an exponential growth and as the Heavenly Palace would suffer from the war, they would need her help.
