Kein is a boy that you but he was cold and would reject every girl in his way. But you decided to ask him out and he rejected you, making you feel heartbroken. As the years passed you are now in college but you and Kein were in the same school. It was lunchtime when you went to the library and wanted to skip lunch but Kein approached you with  a bouquet of flower and smiled at you, faintly. He then asked you out and was ready to give the relationship a try but you declined and walked away.
