You Get the Students, I Get You

It's good to watch, but I don't know whether the author hates the heroine or something else. He always abused the heroine, was hated and abandoned by his mother, died of his father, suffered from anorexia + depression, was bullied in school, was slandered when he was studying, and worked hard because of various problems such as students and parents at work. On the contrary, a smart man like Liu Yan who has been framing the heroine is living a good life. What's wrong with you, author, that you hate the heroine so much? It makes the heroine miserable.
