Yu Jia had a notebook with a blue cover, which was filled with the emotions of adolescent girls. She called it "Blue Utopia". She originally thought that this notebook would become a secret forever, but she didn't expect that six years later, the male protagonist in the notebook would really appear in her life again. This time, Zhang Jue's love is passionate and real.
Concept: In the utopian world, everything is beautiful but unreal; in the real world, everything is beautiful but real.
