What was the point in forgiving himself if it made no difference in how he was treated by those around him? What good would repenting do if the outcome would be the same regardless of if he did or not?

He says nothing, turning his back on Xichen to allow him to leave unimpeded. He doesn't break the tea cups, though he very badly wants to. He wants to be feral and wild for just a minute and destroy this entire house just to sate it, but he refrains. He paces like a caged tiger for a while, until his legs ache and the muscles straining to keep going satisfies him enough to permit himself to rest.

The next time Xichen comes, Guangyao is calm again, though he looks surprised to see him. He hadn't been sure he was even going to come again, but he lowers his eyes and bows politely in greeting, gesturing for Xichen to come inside.
