I recommend A Breeze Like You to you. This was a modern romance novel about urban life. The heroine Luo Weiwei was pure and kind, living an ordinary life until she met the male protagonist, Chen Yue. The male protagonist lost both his hands in the accident, and this situation made the male protagonist feel depressed. However, with the female lead's company, the male lead pulled himself together again, and in the end, the two fell in love. I hope you like this fairy's recommendation. Muah ~😗
