"TILLY, how do you feel?"
"I'm okay now, Father," Tilly assured her father with a smile. "My body temperature is back to normal."
Currently, they were having tea in the "family room." Her father heard about her dispute with the Belington Siblings. He wanted to hear her side so she gave him a full report. But when she told the duke that she used her Mana to protect herself, her father's mood suddenly changed.
She couldn't decide if he was worried or upset that she used her Mana.
"Tilly, don't use your Mana like that again," her father said in a stern voice. "You don't have to fight to protect yourself. That's the job of our knights. And you're engaged with the strongest captain in the empire. How many times do I have to say that your Mana isn't fit for combat?"
She couldn't really understand why the duke was so strict when it came to that.
