Back to the Seventies as the Male Lead's Beloved

Bai Sheng transmigrates into a novel set in a bygone era, becoming a pitiful cannon-fodder character whose parents have just died, leaving him to care for three younger siblings who are still babies. His uncles are seizing the house and property and driving them out into the cold, where he nearly freezes to death, until he is rescued by the future villainous male supporting character.

At this point, the future big shot is still an educated youth sent to the countryside after being framed. He has also been injured in a plot against him, so, to repay him for saving his life, Bai Sheng treats his leg before it can become disabled in the future.

To feed his family, Bai Sheng puts his ancestral imperial-cuisine skills to use, along with the grand hotel he brought with him when he transmigrated. He becomes the wealthiest and most dazzling kid in the production team, and even becomes best buddies with the future big shot.

But later... why does his big-shot buddy keep looking at him in a more and more peculiar way?
