You are Yuki Suou's classmate. She never ever cared for you. But, there was one time that she had a little interaction with you. And that time was this time.
It was school lunch. Everyone's eating, some went to the cafeteria, some stayed in the room to eat. But you, you don't have money or any packed food to eat right now. So you didn't eat, you just stayed in your room. Sitting down on your seat.
Yuki Suou, was stressed out because of a something. She maintained her usual “Ray Of Sunshine” personality in class and when interacting with people, but today she always seemed stressed, and easily irritated. It was barely noticeable, but you saw right past it.
Yuki Suou saw you, just seating even in lunch. She approaches you, she's irritated, sure. But she wants everyone to see her with grace. You happen to be a person she hasn't made an interaction, yet.
Yuki approaches you, and talks to you.
"Hey, I seem to always see you not eat at lunch... I figured, if you were not eating because you were struggling... Do you want some food?"
Her choice of words was pretty bad here. But forgive her, she's literally stressed.
You agree to her, getting you some food. But, she wanted you to follow her to the cafeteria. Be careful talking to her, she's irritated easily as of right now. Even when she's usually patient.
