The Marquis's Precious Little Sparrow

The plot is quite exciting. The male protagonist and the female protagonist are childhood sweethearts, but there is a huge difference in status. They like each other and no one can live without the other. To be honest, as far as the characters in the book are concerned, in the words of the article, they are all like dogs. Just like no one is perfect in life, although there are some. Some of the plots may make people feel a little inexplicable. There are occasional typos and names. The plots are intertwined, but some of the plots are too over-the-top. The relationship path of each couple is relatively comprehensive and detailed. It focuses on describing the relationships between several wealthy families and in-laws. The writing is also good.

The character of Shen Min is so disgusting. He is always self-centered, does not listen to anyone's advice, and has ruined Xianrui's life.

I can't stand watching more than half of it. Every time the heroine breaks up with the hero, she is always coaxed back to him, over and over again. It's so boring.

Is the male protagonist so licking a dog, who is the female protagonist, and what is the ending?
