Si Xinyi, a devoted fan of Daiyu from Dream of the Red Chamber, wistfully closes the copy of Dream of the Red Chamber he's read countless times, longing for Lin Daiyu to live a carefree, happy life.
But after simply falling asleep, Si Xinyi wakes up somewhere unfamiliar.
Just as he figures out who he is, two pieces of news leave him stunned.
The bad news is that he has transmigrated to ancient times.
The good news is that this is the world of Dream of the Red Chamber, and he's a prince.
What else is there to do? His first priority is to find out how Lin Daiyu is doing!
First, he'll find a way to bring Lin Ruhai back to the capital and secure him a place in the cabinet.
With her father backing her, Lin Daiyu won't be bullied!
Then he'll find Lin Daiyu a good husband, so certain shameless people won't get ideas about her.
After considering everyone, he decides that no one in the entire capital is worthy of Lin Daiyu.
Only then does Si Xinyi belatedly recognize his own feelings.
He'd only meant to protect Lin Daiyu, but somewhere along the way, that turned into love.
When Daiyu is six, she meets a handsome young boy who solemnly promises her, "Little Sister Lin, I'll protect you from now on."
From Jiangnan to the capital, from the Lin residence to the imperial palace, her young companion spends his whole life keeping that promise.
