Was there any romance novel that could be found based on part of the plot? Please recommend! I'm extremely grateful!

I only remember part of the plot. Please help me ~ Thank you, thank you!
The female lead transmigrated to become the main concubine. The male protagonist had a scheming concubine that he liked. The female protagonist pretended to be vulgar every day and even fought with the concubine. Once, when she followed the male protagonist into the palace, the emperor asked someone to bring a pile of rewards for everyone to choose from. The female protagonist took a fancy to the male protagonist's painting at first glance because the female protagonist's younger brother liked the male protagonist's painting very much (of course, the female protagonist did not know that it was painted by the male protagonist). Moreover, the female protagonist's younger brother was crippled. Once, the female protagonist cured her brother's leg and was about to recover. However, the female protagonist's enemy (stepmother?) He captured the female protagonist's younger brother and wanted to remove the tendons in his hands to prevent him from painting. Then, in order to protect his hands, the younger brother kicked his legs. The enemy then removed the tendons in his legs, causing the younger brother to be unable to walk in the future.
