Ogiwara Umi is a typical sixteen-year-old girl with an exceptional older brother. Ogiwara Haruto is a rising star actor, and girls call out his name wherever he goes. This situation would be challenging for any younger sister, but Umi has it especially tough ~ she not only suffers from a brother complex, but she is genuinely in love with her brother! Yet perhaps the more pressing question is ~ does Haruto feel the same way?
