Azusa has just been discharged from the hospital and is frolicking on the beach in Jushi, finally getting her freedom. Her older sister, Kozue, looks after her. Her father Shuhei moved from Tokyo to Jushi to provide a peaceful environment for his sick daughter. One day Azusa meets Tomita, a high school student, and falls in love with him at first sight. This is a masterpiece of literary lyrics, about two sisters living with bright and pure love, looking at the approaching shadow of death and giving all their feelings to limited youth.
