Wen Che relies on Lu Xun for mental guidance.

Only she can turn his chaotic pain into clear tranquility.

He wants her comfort all to himself, forever.

First, he caters to her tastes: preparing a sunlit room, cooking food she likes, and bringing an extra umbrella on rainy days... He waits quietly for her to fall for him, then proposes a match.

Then he waits for her to mark him.

He thinks he can stay in control forever.

Even if their match is canceled, it will only be temporary.

Until she marks her exclusive Sentinel, who turns out to be the younger brother he hates most.

*

Wen Yao has known since childhood that he is an illegitimate child.

Everyone around him says his genes are inferior and that he is a stain on the Minister of Finance's reputation.

So he feels no guilt about falling in love with his older brother's matched Guide.

After all, inferior people are born to do despicable things.
