Please Don't Date Him

An AI-controlled, household appliances developer in Pelican Electronics, Seo Ji-seong, has dreams of living a perfect life like a well-developed program.

Working on an Artificial Intelligence refrigerator with voice-activated features, she inserts a super sensor chip which was lost by National Intelligence Service into a refrigerator, and an "Ancestral Spirit" program that picks scums instead of telling the freshness of vegetables is developed. So, Ji-seong finds out that her deemed perfect fiancé Jeong-han was actually not her Prince Charming.

One day, Jung Kook-hee, a firefighter, with no social media record, whom the program couldn't analyze, shows up. Ji-seong is skeptical about him, as there is no trace of his past on the internet.
