I recommend to you the novel " The Divine Doctor's Little Sweet Wife Dressed as a Prince ". The female protagonist, Yan Shihan, transmigrated to the ancient era and was bound to a cute pet system. To complete the mission, she had to hold hands with the disfigured and crippled male protagonist, kiss him, and finally marry the male protagonist and have children. Although the male protagonist was disfigured and crippled, he looked exactly like the female protagonist's dream lover. The female protagonist had to marry him. Although the story was a little fantastical, the love line between the male and female leads was very sweet and heartwarming. I hope you like my recommendation.
