Summary:

Ami's brother Chihiro has always been the cutest in the family, but ever since he was a child, he has often been mistaken as a girl. Now Chihiro is a model for women's clothes and everybody likes him. Even the boys at school prefer him, who wears the girl's uniform at school, over his sister. That's why Ami's love life has always been a failure due to boys who compare her to her brother. Easily tempted by cute guys, Ami still doesn't realize that among boys who dumped her, her unrelated brother sees her as more than a sister and loves her deeply.
