Yuan Xiangqin: An ordinary high school girl, because she has had no mother since she was a child, and has been dependent on her father, her life is said to be very hard (who knows if she is hard or not), so her grades are so-so, and her life has been smooth for 18 years. Her biggest wish in life is to marry the person she loves and inherit her father's "Happiness House", so that the family can live happily.
Jiang Naoshu: A genius with an IQ of 200, he has received perfect scores in all exams for the past three years (How can there be such a person in the world?). No matter studying or other things, it seems that there is no one he can't do, and there is no one he can't get first. In the past 18 years, he has never known what failure is. It seems that nothing can stump him, so he has never known what "desire" is.
Mother Jiang: Naoki's precious mother. It's strange how such a mother could give birth to such a precious child like Naoki. It can be seen that geniuses and idiots sometimes reach the same destination by different paths.
