After their parent's death, Junna live together with his twin sister, Senna. They attend Sakurahama Private High School and have many good friends. Junna lost all his memories before the accident that took his parents life.
One day, a girl named Inohara Haruhi showed up and called Junna as onii-chan (older brother). She was introduced herself as Junna's childhood friend. Since Junna lost his childhood memories, he can't really remember who is Haruhi actually. But Junna remembered Haruhi's name even before she said her name.
Strangely Senna don't want his brother to remember his past. One day Junna discovered an old family photo album, and found that there is no single picture of Senna. All photos in the album show Junna, his parents, and Haruhi !
So who is the real younger sister of Junna?
A very sweet story about the strength of hope. Recommended for age 13+. My rating : very good.
