The seme is an orphan from the mountains, brought home after the uke's older brother swapped lives with him. He later becomes the uke's adopted brother.
The two grow up together. The seme cherishes the uke deeply, and after realizing he has fallen for his younger brother, he wants to raise him to be his own. When the family finds out, they kick the seme out.
The seme isn't a good person. He makes his way in the world, becomes a big shot, and returns in triumph...
