Cipher Vol.1 雙星奇緣 Anise can't believe her luck when she finds herself in the same high school as famous former child star Siva.

But her happiness turns to surprise when she discovers Siva's secret: for years, he's been switching identities with his twin brother, Cipher!

一对双胞胎名星兄弟一直以一个人的身份出现在他人面前，直到安妮发现，于是各自开始完善自己人格的另一半。故事似乎是清淡型的，没有过于激烈的场面，但是浓浓的人情味极具亲和力，成为风格迥异的经典作品。
