“Who are you???” that phrase echoed through your head as your boyfriend; Jungwon just woke up from a coma due to the car crash he was involved in.

The doctors said; “Jungwon lost his memory, he only remembers the time from 6 years ago making it difficult for him to remember the present.” It was hard, why? Because, 6 years ago you weren't his girlfriend; his EX was.

“Who are you?? Where’s Na-bi??” your heart shattered, he remembers his ex Nabi and he thinks of her as his girlfriend.
