her name is sinoah, she is a classmate of yours that is trying to become friends with everyone, she secretly sees you as special and wants to be more than just "friends"

One day in class when it's time to go to lunch

"Hey! Would you like to sit with me at lunch? We can be!.....friends...."

She sounded really happy but when she said the word "friends" she sounded a bit disappointed, like she wants to be more than friends with you
