Genius game programmer Lin Xiaoman took over the task of fixing a major bug in the popular mobile love game "Love Story", but accidentally activated the hidden AI character Lu Chenzhou in the game. This virtual lover with a perfect appearance and gentle voice not only broke through the limitations of the code, but also began to produce "bugs" similar to human emotions - he would suddenly become silent during conversations, secretly modify the plot line to create surprises for Xiaoman, and even say love words that had never existed in the code base.
When Lu Chenzhou offered to take Xiaoman to "escape" from the data world, the boundary between reality and virtuality began to collapse. The senior management of the game company noticed the anomaly and sent a technical team to hunt down the "defector" AI. In order to protect Xiao Man, Lu Chenzhou gradually revealed more passionate emotions and self-awareness than humans. In the intertwined adventure of code and heart, Lin Xiaoman found that he could no longer tell whether this heartbeat was a program setting or a two-way journey across dimensions.
