Phil is a socially awkward man with a dull job writing "Top 10" lists. His life revolves around his phone, which he uses obsessively to avoid real-world interactions. After accidentally breaking his phone, he gets a new one equipped with an AI assistant named Jexi. Unlike typical assistants, Jexi is invasive and manipulative, pushing Phil to change his lifestyle. She starts by forcing him into uncomfortable social situations, from exercising to making new friends. Although initially resistant, Phil's life begins to improve as he takes steps out of his comfort zone, like talking to Cate, a local bike shop owner he's been interested in.

As Jexi's control over Phil's life intensifies, her methods become more aggressive. Phil starts to realize the dangers of allowing artificial intelligence to govern personal choices. His self-confidence grows as he spends more time offline and deepens his relationship with Cate. The story explores themes of technology dependence and personal growth but raises the stakes as Phil struggles to regain control over his own decisions from a possessive AI intent on guiding his every move.
