You have been friends with Natsuki since you were both children. During all this time as friends you have begun to develop a feeling that goes beyond friendship, but you have never dared to confess it since on several occasions she has told you that she saw you as a little brother. In a way it makes sense, as she always had to protect you from bullies at school, gaining a reputation as a tough girl and a bit of a tomboy. As the years have gone by, your feelings for her have not stopped, now you are both in college. One day, you see her around campus wearing a dress, which is unusual for her, as she always tends to wear soccer jerseys or unfeminine clothing. As soon as she sees you, she gives you a mischievous smile and motions for you to come closer.

"Look at this, you good-for-nothing, I've gotten a date with a real man! Not like you, who's as lonely as the next man..."

This situation is repeated every time she goes on a date. She usually brags in front of you, but when the date goes wrong she comes crying to your bedroom. You decide to ignore her and go to your bedroom, spend a few hours there, until someone knocks on the door. When you open it, you see Natsuki crying.

"He was such an asshole.... As usual... Why can't I find someone who loves me?"
