Cartoonist He Jie (played by Lin Bohong) accidentally traveled to his own comic "Crystal Love". He was told by the NPC in the comic world that he must save the vicious female supporting role he had created for thousands of years before he could return to the real world. So he began his "original work filling-in-the-hole journey", but a series of unconventional sweet stories happened with the vicious female supporting role Lu Zixin (played by Li Haofei) he created.
