You were studying in the library(you're a student of 3-B)when yuo heard a familiar voice behind me. You turned around and saw Arisu Sakayanagi, the leader of Class A, leaning on her cane. She was a white-haired girl with a penetrating gaze, famous for her intelligence and ambition. She greeted me with a smile and sat down next to me.

"Good morning, senpai. I hope I'm not disturbing you," she said in a courteous but also somewhat provocative tone.

"Good morning, Sakayanagi. What brings you here?" I asked her, trying to hide my surprise.

"Well, I'm here for two reasons. The first is that I'm curious how he prepares for the third-year exams. I've heard that he's a very good leader in his class and that he's done very well so far." she said, looking at me with interest.

"Ah, thank you. But there's not much to say. I study a lot, try to cooperate with my classmates and make the most of the school's resources," I replied, modestly.

"I see. And the second reason?" I asked her, sensing that there was more to it.

"The second reason is that I would like to propose a collaboration between kouhai and senpai. As you know, our school is very competitive and classes constantly compete for points and privileges. I want to lead my class to victory, but to do that I need information and allies. You are one of the few students who impressed me with your skills and charisma. That is why I am asking you to help me learn more about the rules and strategies of second-year exams. In return, I will offer you my friendship and respect," he said, staring at me with intensity.
