The heroine is a has-been screenwriter who participates in a celebrity × amateur AI love experimental variety show in order to become famous. The "AI boyfriend" she wins is actually a top actor pretending to be himself - he has been secretly in love with her for many years and bribed the show crew to pursue her just to be legitimate.
The sweetest point: the male protagonist uses his AI identity to talk about love without restraint, and the female protagonist is excited while thinking that "the program is set up well"; after falling out of the game, the male protagonist feels aggrieved: "None of those words were written in code."
