The protagonist has the ability of "character embodiment", but this ability comes from an unfinished street novel she wrote. The core villain in the novel (the sinister tyrant) travels to the real world and believes that the heroine is the "mysterious heroine" of his novel. He needs the heroine to "fall in love" with him so that the novel universe in which he lives can be stable. However, as a science student with clear logic, the heroine firmly believed that this was an illusion, and tried to send him back using scientific means such as "psychiatrist" and "police intervention". The male protagonist uses his "golden finger" (absolute understanding of the heroine's novel setting) to constantly create trouble for the heroine and then solve it in reality, trying to show his charm in front of her.
