The heroine Bai Yueguang type. The male protagonist is patriarchal, combining pure love and madness. It's the misunderstanding that if his wife has someone else's child, he can raise it together.
The heroine is a heartthrob and a master of mathematics who doesn't know it, but she is always suppressed by the geniuses around her and loses her confidence. She backs off again and again, and just starts by solving questions.
Keep your math advantage, and you will be really strong later on. (The heroine also has a lot of dark sides. She is not a bright and upright character, but more of a villain and supporting actress, but she is also quite real.)
Except for the heroine's fiancé, who is a zang cucumber (in a certain reincarnation, the two of them also lived together, and the heroine also knew about her fiancé's virtues. If she hadn't met in person, she would have probably pretended to be deaf and dumb until she got married). Except for the yandere, the other male characters are devoted to the heroine.
The writing style is clear and elegant, like the writing style of a fairy tale, written with realistic brushstrokes. It's been a long time since I've seen such a gentle male protagonist. He kept getting closer to the female protagonist and never looked cold after the breakup. The heroine is beautiful, strong and miserable, and her family is wealthy, but her father does not care for her and her mother does not love her. She has been accustomed to emotional isolation since she was a child so that she can isolate herself from harm.
