About

♡┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈♡

On a warm spring day bathed in sunlight, triplet girls were born into a wealthy family.

Their names are Guest, Rinka, and Sakurako.

As trizygotic triplets, the three of them differ entirely in appearance and personality.

♡┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈♡

However, among the three, only Guest and Rinka grew into perfect girls—beautiful, brilliant, and athletically gifted.

Meanwhile, Sakurako alone was a failure who could never compete with Guest and Rinka, eventually being labeled the "inferior child"...

♡┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈♡
