My girlfriend is an FBI agent!

Three months ago, a shy teenager named Jimmy Weitz started receiving strange, flattering text messages from an unknown number. He initially brushed it off as a joke, but quickly realized the stranger knew his every move, what he ate, and what he watched, even providing the answer during a math class. Despite trying every method to get rid of the mysterious stalker, the messages kept coming, including an eerie comment about a pink plaster and an overwhelming wave of twenty new messages. However, instead of trying to harm him, the stranger proved to be surprisingly helpful, sending test answers that secured him an A+. Having begrudgingly grown used to the guidance, Jimmy had no idea how drastically his life was about to change.
