Yan Yunshu unexpectedly transmigrates into a book as the fake young master, a cannon-fodder character who is doted on and spoiled rotten.
To show off his standing in the family, he humiliates the real young master when the latter returns home.
After marrying the Second Prince, he is treated cruelly and only then realizes that his adoptive parents had been kind to him solely to use him to curry favor with the powerful.
This twists the fake young master's heart even further. He keeps finding ways to bully the real young master, until the Second Prince fails in his bid for power and the fake young master's entire family becomes cannon fodder.
Meanwhile, the real young master earns great merit in helping the new emperor ascend the throne and becomes the dynasty's only noble with a different surname from the imperial family.
When Yan Yunshu arrives, the real young master has just returned home and been sent by the fake young master to the servants' quarters.
Yan Yunshu jolts and immediately rushes to the servants' quarters.
Looking at the boy in coarse clothes, whose striking presence remains undimmed, Yan Yunshu nearly gets a nosebleed. If he grows up a little more, he'll be absolutely gorgeous!
Xie Heng frowns at Yan Yunshu. He thinks he hears Yan Yunshu speaking, but doesn't see him move his mouth. He assumes it's his imagination, but then things get strange: he seems to be able to hear Yan Yunshu's inner thoughts.
Yan Yunshu takes him back to his courtyard and shares everything with him. As he goes on sharing, he suddenly pauses and looks at him expectantly. Xie Heng hears Yan Yunshu "say": He isn't going to think I'm showing off like some scheming green tea, is he?
They eat and sleep together, growing up side by side, until their eighteenth birthdays. Yan Yunshu pretends to be drunk and kisses him. With teary eyes, he looks at Xie Heng, and his inner thoughts come through as usual: Ah! That was so good! I want to sleep with him so badly!
All restraint crumbles in that instant, and Xie Heng gives him exactly what he wants.
