The novel begins with an 18-year-old male protagonist being arranged to be a live-in son-in-law by the old man who raised him for 18 years.

。The age of the protagonist and his son is unknown, so I can't tell what kind of novel it is. If you can provide more information such as the plot, author, publication date, etc., I will try my best to provide you with a more accurate answer.

The protagonist of the novel saved an old man who was in a car accident, but the old man was terminally ill and would not live for long. The protagonist recognized the old man as his godfather. This was a classic plot that was usually used to show the kindness and compassion of the protagonist. In the novel, the protagonist may face some choices, such as whether to save the old man or whether to give up. These choices will determine the fate of the protagonist. In the novel, the protagonist might find the old man very precious because he had something that the protagonist needed, such as experience or wisdom. The protagonist might decide to acknowledge the old man as his godfather because he wanted to use the old man's experience and knowledge to help him grow. This plot could also be used to show the growth and transformation of the protagonist because the protagonist learned many things in the process of saving the old man, such as responsibility, courage and compassion. These experiences would help the protagonist better cope with various challenges in his future life.

Hey, let me recommend a book for you called " The Rich and Powerful Contract: The President's Wife." The male protagonist became the president at the age of 18, and the female protagonist married him at the age of 18. Later, when she was 23, she gave birth to his child, but she left. When she returned to the city with her child, she found that her ex-husband had already remarried, and the bride was actually herself. The story was full of love and family plots. The male lead seemed to dote on the female lead, making people feel very sweet. I hope you like my recommendation.😗

I recommend You Are My White Moon to you. It's a novel about all kinds of things in the world.

Of course, there were many novels with 17-year-old male leads and 3-year-old female leads. This type of novel was usually set in a fantasy or sci-fi world. A larger age gap between the male and female protagonists allowed them to have more opportunities to communicate and interact. These novels may involve some complicated plots and character relationships, but they can also be full of romance and warmth. For example, the following are some recommendations for novels with 17-year-old male leads and 3-year-old female leads: 7th Grade Tail-Qinghan 2.

Son-in-law of the First Wealthy Family. I especially recommend this novel about urban life written by an old monk from the Jokhang Temple.

I experienced a different life when I was a live-in son-in-law, but I also gained a lot of valuable experience. As a live-in son-in-law, I need to respect my wife's family and live in harmony with them. At the same time, I also need to work hard to create better living conditions for our family. Life as a live-in son-in-law wasn't smooth sailing. Sometimes, I would feel inferior or embarrassed because of my identity, but I also learned how to deal with these emotions and how to express myself in front of my wife's family. The few years of being a live-in son-in-law was a very precious experience in my life. It made me understand the importance of family and made me cherish my family more.

The name of this novel was " Snow Fall Rebirth ".

I recommend "Rebirth of Trash: The Unscrupulous Thief is Too Black-bellied" to you. The male protagonist of this novel was also raised by an old man. The old man's martial arts are strong, and the male protagonist also has a certain level of martial arts. The story was also set in a different world. I hope you like this fairy's recommendation.
