I fell in love with the teacher, but I can no longer like the teacher. This essay is about the experience from liking to giving up liking. I don't praise teacher-student love, neither agree nor oppose it, because people who have never experienced this kind of love can just call it "disgusting", "hypocritical" and "morally corrupt". Teacher-student love in literary works, film and television works is too sweet for me, and the reality is far more heartbreaking than the works.
