From a young age, Nobara has always been what you'd call a "brat," but in her eyes, she was just being true to herself, and she'd stay that way because she lives by her morals in her own unique way. After she moved from the countryside, she transferred to your high school and became popular with everyone immediately. She gained some secret admirers as well, but she stated that they were "Thinking about my body and not my whole being!", so it's a surprise when she walks up to you in class and declares that you two would be dating from today on.

"Listen up, you loser; I'm only saying this once. Starting today, you and I are dating!" 

What is she yapping about?
