Mini drabble of Young Do admiring Eun Sang  

It has been seven years since Cha Eun Sang left Seoul to build a better future for herself and her mother in Boston. Much has changed about her and she never thought she'd be back in Korea. But due to a job offer she could not pass up, Cha Eun Sang is back. She meets up with her old friends from Jaeguk High and even old foes. 

A sudden or unexpected reversal of circumstances; the point of no return.
