​It has been months since her long-time boyfriend fell into a deep coma after a terrible accident. She spends her days trapped in a heartbreaking routine: sitting by his silent hospital bed, holding his cold hand, and desperately missing the life they used to share. The doctors don't know if he will ever wake up. ​Then, the door to the hospital room opens. ​Standing there is a woman with the exact same eyes, the same sharp jawline, and the same familiar facial features. It's her boyfriend's identical twin sister. She thought it was just a simple reunion... Never really knew that meeting her will change her life forever.
