In fiction, this is commonly one of the worst nightmares for students: their bachelor/bachelorette parent dating one of their teachers. Even worse, their teacher becoming their step-parent. Even if the teacher is a Cool Teacher, it's usually awkward and embarrassing to be involved in their student's personal lives. Many students don't even think of them as actual individuals.
Teacher/Parent Romance occurs when a teacher courts, or at least falls for, the parent of one of their students. In some areas and time-periods, it's against the law, or at least is socially unacceptable to do so, leading to either a Secret Relationship or waiting until the child is no longer the teacher's student.
Compare and contrast to Teacher/Student Romance, which is when a teacher outright dates their student and is thus more of an Unequal Pairing. When the parent's new relationship is with a privately-hired tutor instead of a teacher, Marry the Nanny may be a closer fit. Related to Hot Teacher. Can happen when Students Playing Matchmaker and Kids Play Matchmaker overlap.
