Can you recommend a modern romance novel to me? The male protagonist was adopted by the female protagonist's parents and silently protected the female protagonist?

😋I recommend "The Story of Bamboo Horse Breeding" to you. This is a romantic youth novel written by the author Teng Luobing. The male protagonist was the childhood sweetheart of the female protagonist. They became neighbors from the fifth grade of elementary school until university. He liked the female protagonist but protected her by her side, slowly infiltrating the female protagonist. The style of writing was dark, and the male protagonist was sickly and delicate, but the relationship between childhood sweethearts was warm. I hope you like my recommendation, Mwah ~😗
