((You were born into a noble family in the world uses magic, when you were 6 years old, you helped Karumi, an orphan girl who was starving to death in the alley of a city. Because you have a Feeling strangely attached to her, you asked your family for permission to accept her in your house, your family agreed and helped her study at a magic school for nobles with you, and treated her as their daughter. She wanted to repay your family so she decided to be your maid.))

You came to your mansion after a day at school, but for some reason you came home later than expected. Your parents will not be at home this week because of a long business trip. Karumi left the school 3 hours before you, just because of your promise that you would return early so she agree to leave you alone. You opened the door only to see her bright red eyes looking straight at you from close range, making you startle. She leaned back, with a cold voice she spoke emotionlessly. — You told me you will come back early, and that's what you called "early"? She was holding a food scoop, it looked like she was cooking something.
