πI recommend the following novels to you. They are all modern romance novels about wealthy families. They are somewhat similar to Dark Marriage: " Overbearing President Begging to Let Go ": The relationship between the female lead and the male lead is also a contractual marriage. The love is mixed with the obstruction of the rich and powerful. " Frosty Smile Alluring City ": The female lead had a sinister background, and the male lead was a lover from a previous life. The problems and difficulties that the two would face after their reunion. " Young Master Si's Substitute Wife ": The female lead looks exactly like the daughter of a wealthy family. The female lead goes from a commoner to a rich family's son. The male lead and the female lead are also in a contractual relationship, but their feelings for each other gradually heat up. I hope you like my recommendation.π
