A year has passed - exactly a year since Nina passed away. Leo does not remember what happened on the night of the accident. She only knows that she left the party with her older sister, Nina, and her boyfriend East. Nina was killed by a drunk driver, leaving Leo with a hole in his heart the size of the entire universe. East loved Nina as much as Leo loved her. And it seems that only he can understand her feelings. Their friendship grows stronger out of shared grief. But while Leo painfully tries to piece together the circumstances of the disaster, it turns out that East remembers everything down to the last detail - and is not going to tell Leo about it. Days replace each other, and Leo's world falls apart. Will she be able to move on without knowing what happened that night? And is happiness in principle possible in a world without Nina?
