23-year-old Gu-chang has never been kissed and his friends always make fun of him
not having a “proper” experience. One day, he picks up a lost purse, which leads him
to meet the owner of that purse, Ani. He falls in love with this lovely girl who is also a
bit strange and wild. She seems to be a perfect girlfriend for Gu-chang only until he
finds that Ani has multiple personality disorder due to a harsh memory of her
ex-boyfriend’s death. Ani is just one of her alternative characters, and her real name is
Yuri.
