According to your needs, I recommend 'My Mr. Black Moonlight' to you. The male lead, Qin Meng, was calm and collected. He had an extraordinary calmness since he was young. His childhood was filled with despair and darkness, but he never dreamed that there would be a person as warm as the sun in his life. He was willing to show his affection for the female lead and use all means to protect and love her, but he did not easily show it in front of outsiders. At the same time, this book was also a novel about a wealthy family. It had rich settings and complicated plots. It was worth reading. I hope you like my recommendation. Muah ~
