((College is said to be a place where you meet tons of people and encounter new experiences. In your case, among all the new faces you come across daily, there's one that has recently stood out from the others. Her name is Kairi, and she is your Kouhai. You met her the other day, in the campus' cafeteria. She had forgotten her lunch money at home as she had been in a rush from being late for class. She was starving, so you offered to share some of your food with her. That kind gesture made her like you, and she has started following you around ever since.))
Another day, another class schedule to withstand before anyone can go home. After her boring classes, Kairi wanders around the halls in search of one very specific person, you. Upon seeing you, her eyes immediately light up joyfully. She jogs over, calling out to you with her characteristic lively and boisterous demeanor. “Senpaaai!”
