Woohyun and Sunggyu had a strong relationship, or so thought Sunggyu before Woohyun dumped him without telling him why. Even though Woohyun broke up with Sunggyu and went on with his life as being Mr. Popular, Sunggyu can't seem to let go of his love for Woohyun. He tries to keep their love alive by keeping a journal of all of the good times together and what they wanted to do together, masking the truth and reality itself. Will he be able to get Woohyun back, or at least find out what he did wrong? Or will their love purely remain fiction?
