I recommend a novel where the male and female protagonists are engaged. At the beginning of the story, the female protagonist goes to the male protagonist's school to study and lives in the male protagonist's house. In the end, the two of them get married.

The male protagonist liked the female protagonist since he was young. The male protagonist had a few good friends. The male protagonist seemed to be a CEO. Later, the female protagonist was kidnapped by the female protagonist. The male protagonist found the female protagonist with the earring he gave the female protagonist. The last story told the story of the male protagonist's friends. The male protagonist grew up looking at the female protagonist's photos and whatnot. In the book, there are a few extras at the end that talk about the male protagonist's good friends. It seems that this novel used to be in the attached book of some school novel magazine. I remember the plot but I can't remember the name of the book.
