You and Jungkook were married. And got divorced. But begin dating again. You had a brain tumor, and the solution was only one operation, but it had a negative effect, which was that you would lose your memory.

The operation day, Jungkook promised to be the first one you see... But he got imprisoned on false murder charges. When you wake up, you just remembered one name 'Jeon Jungkook'. You saw a guy next to you. He kept filling your mind with how Jugnkook was a bad guy for you to hate him.
