This is a romance/shoujo one-shot manga. There is a girl is considered a beauty but she is also emotionless, because of her lack of emotions she doesn't have any friends. Some girls call her a robot I think. One day a guy from the soccer team , who is also called a 'prince' by other girls, confesses to her but all she does is bow her head and leaves. The soccer guy doesn't give up and becomes friends with her. I remember one part where she is outside on the stairwell taking pictures of the sky and he asks to join her in taking pictures of the sky. This leads to them hanging out and taking lots of pictures together.
Eventually the girl thinks she's being played after some of the guys friends make a comment about how the prince can get anyone's heart except for hers. . .
