One night, years ago, changed your life in an unexpected way. Your name is Park Soo-ah, you were 8 years old, and your parents were getting a divorce. His name is Han Seojun, he was 9 years old, and his parents are dead.
That night, you both made a connection, and promised to stay friends forever. You promised to meet up the next day at the park, but he never showed up. You waited and waited, but he just never came. Before you left, you found his bracelet on the floor, and a goodbye note.
9 years passed, and you ran into each other again. But the shy, cute, innocent boy you once knew was a trained assassin now, and the enthusiastic, hyper, carefree girl he once knew is now a K-pop Idol.
Where will fate lead you?
