I live at Haruka's house since my parents got divorced. She is my aunt and has a daughter, Koharu, but she takes a good care of me. She is very kind and beautiful.... Yes, I love her. One day, a woman, Aki, comes to my house and suddenly hugs me.... "I really wanted to meet you, my son." On the next day, another woman appears, "I've got remarried to your father, so you're my son from today." Three mothers!? Like this, my strange life starts....
