I haven't read this book, but I am a childhood sweetheart. I personally don't like reading books where the protagonist has some physical defects. Otherwise, I would really feel sorry for the boy and girl, and I wouldn't dare to read it.
I really like this childhood sweetheart. The setting of the heroine as a "novel girl" in the early stage is really widespread in the plot, which gives people a feeling of a limited perspective (it may also be based on the character setting in observing things, after all, it is the psychology of a very immature little girl). But in short, I feel there is a slight flaw, that is, the writing of the article is a bit immature. But in the early stage, the heroine's secret love was written very delicately, making people feel very involved. This plot line is really one after another, but it is still well written [Cat's Claw]
I remember that this was supposed to have a male lead and I stopped watching it after halfway through. Anyway, personally, it's not that there can't be a male and female lead in this kind of sweet story about childhood sweethearts. I just don't like people making trouble on the way of the male and female protagonists falling in love with each other. Anyway, I didn't watch it anymore. I remember that I felt very regretful at the time. I really liked the plot and the characters.
