Prologue Life's full of surprises four girls are surprisingly brought together, by chance. Each has their own unique personalities. Iba't iba ang istorya ng buhay na siyang nag patibay sa bawat isa. Parang isang puzzle na nabuo nga magkasama sama, iisa naman ang nais marating. Bawat isa'y may pinagdadaanang pagsubok ngunit dahil sa pagkakabuo ng kanilang samahan, walang humarap nang mag-isa sa pagsubok. Ang kanilang motto, "we are sister. Your problem is our problem, your joy is our joy, and your victory is our victory. No one should feel alone because we are one."
