High-IQ biological heir seme?? Outwardly aloof but gentle with the seme, fake heir uke
"He stole my life, so he should give himself to me as compensation."
When Xie Zhiheng was fourteen, he unexpectedly learned that he was the rich family's biological son, switched at birth with another child. That very afternoon, his biological parents brought him home.
Although his parents kept saying how sorry they felt for him, they showed no sign of wanting to send the fake heir away. Xie Zhiheng could only think how ridiculous they were. They were heartbroken for their biological son, yet couldn't bear to part with the fake son they'd raised for fourteen years.
"Zhiheng, this is your older brother, Fu Jingze."
Looking at this brother he'd just acquired, Xie Zhiheng smiled at him.
"Brother, you stole my life, so you should give yourself to me as compensation."
Looking at the cunning, aggrieved young man before him, Fu Jingze smiled helplessly.
"Giving you this lifetime of mine isn't enough. I'm willing to give you my next life, too."
Content warning: The seme's biological parents treat him well, but still favor the uke.
The seme resents the uke a little, but not much. He isn't unreasonable.
The uke matters most to the seme, and he is somewhat cold toward his biological parents, too.
