春の桜(Haru no Sakura/ Spring's Cherry Blossom) [Wattys2015]

One summer break, the last week of July, a 15 year old girl named Sakura was returning to her home in Japan. She lived somewhere else since she was one. She hasn't seen snow, autumn or even spring. Her parents left ahead of her to make some arrangements. Meeting new people in a music school, she learns that within her, she has a curse. Can the music unlock her curse? Or does she have to kiss her dear prince to break the spell?
