My husband had a crush on me throughout his youth, and his diary was filled with everything about me. He held a lavish wedding for me, but never got around to registering our marriage. For the hundredth time, I watched him act intimately with his female disciple and finally lost all hope. I decided to leave, but unexpectedly discovered I could talk to him at seventeen. When he learned I was leaving, his younger self did everything he could to make me stay. I resolutely boarded a plane and began a new life. Meanwhile, my husband discovered the secret of the diary. His seventeen-year-old self demanded to know why his thirty-year-old self was so foolish as to let true love slip away. The diary became a bridge between past and present, intertwining pain and regret, until he finally embarked on a desperate quest to win me back.
