Intimate, But Not A Friend

All it took was a kiss to turn Misaki's life upside down... It was during their final year of high school when Asahi changed bright, fun-loving Misaki's life forever. Kissing his best friend and proceeding to touch his body, Asahi didn't realize that he had made Misaki aware of his own nature. Misaki is crushed when he goes to see Asahi and finds him with a girl. They end their friendship, and five years quickly go by.
