I Transmigrated into a Book, but Why Am I the Heroine's White Moonlight?

[Transmigration + one heroine + no System]

(Important note: the heroine is his fiancée, Ning Ruyu, not Bai Yuyan!!!)

(No System means the protagonist won't be all-powerful from the get-go. If you find the early story slow, feel free to skip ahead to Chapter 56 or 101.)

(This is my first time writing a story, and I hope I can make all you handsome readers happy.)

Gu Chen was one of the millions of overworked corporate wage slaves on the banks of the Huangpu River. After an inexplicable, brief promotion, he became the company's scapegoat!

Then, as law enforcement officers escorted him downstairs, a passing heavy-duty truck that couldn't stand by and watch sent him transmigrating!

He transmigrates into an urban wish-fulfillment novel, only to discover that he's become the rich second-generation son of a second-rate family in Hudu! And the family's only child, no less!

What's more, he's the male lead Bai Yuyan's unforgettable first love!

He'd planned to quietly enjoy the life of a rich kid who had food brought to him and clothes laid out for him. But everyone wants to write him out of the story!

Bai Yuyan: “I want to divorce him and be with you!”

Male lead Fu Jingyan: “Hmph!”

Extra: “Who does Fu Jingyan think he is? Sister Yuyan should marry Young Master Gu!”

Gu Chen: “Hey, don't do this. Don't I already have a fiancée...?”
