Did you recommend any novels with similar plots?

It's the heroine's infatuation. Once, when everyone was riding a horse together, the horse was frightened and stepped on the female supporting character. The female supporting character saw it and pushed the female supporting character, causing him to be trampled by the horse. The male protagonist saw the female supporting character being pushed at that time and scolded the female supporting character. He did not notice that the female supporting character was injured at all. Everyone crowded around the female supporting character and left for medical treatment. After the female supporting character stabilized, they told everyone that the female supporting character had saved her and that the female supporting character had already left. Later, the male protagonist turned the world upside down and could not find the female protagonist. One day, the servant found the female protagonist in the snow pile at the corner of the door, holding the newborn child. In the end, the female protagonist survived but one of her arms was crippled. Every time the male protagonist saw the female protagonist's crippled arm, he blamed himself.
The female lead was a very gentle person. When she left the male lead, she was so sad that she broke down. She kept repeating,"What kind of person is what kind of life is."

Answer 1

I recommend " The Steamed Bun I Picked Up Is the Male Lead ". This modern romance novel tells the story of the female supporting character not following the plot and was adopted by the male lead. However, the male lead did not actually have deep feelings for the female supporting character. The female supporting character was a little orphan with a pitiful background. After being adopted by the male lead, she developed feelings for the male lead, but the male lead could not forget the female supporting character. I hope you like my recommendation.
