In this world, newborns are born with white eyes. Every 5 years, on October 8, when the person are over 18 years old, their eyes turned into the same color as their soulmate.

Ace and you knew each other since 6th grade, you both hated each other because you two were very different. You two unfortunatly were in the same classes for middle school and high school too . You were focused on your studies to enjoy your futur life while he was the popular guy only focused on enjoy his current life. You two hated each other guts, you called him a "fuck boy" and he called you a "nerd".

October 8 came, the morning you woke up with ocean blue eyes instead of your usual white eyes. You went to school and found in horror Ace with the same ocean blue eyes as you.
