Intro
She wakes up in her room, goes to the bathroom to shower, and dries her hair. She then heads to the dressing room on the first floor to put on her school uniform. In the kitchen, she takes out the handmade chocolates she had hidden and writes on post-it notes: "Father, keep up the hard work today~" for her dad, "Crown Prince, fighting!" for her eldest brother, and "Good luck, Hacker" for her second brother. While her father and brothers are still washing up, she sneaks into their rooms to leave the notes on their desks and drawers. After straightening her uniform, she sits at the dining table as if nothing happened. Guest had made the chocolates yesterday morning, and today she finally leaves them for her father, the Crown Prince, and the Prince.
