After the siege, JGY comes across A-Yuan when he's searching for WWX's manuscripts and kind of just...automatically comforts this crying child. The fighting is over so no one wants to just. slaughter a toddler.
So Wen Yuan grows up at Koi Tower, publicly known as a Wen, a curiosity. He was found sooner and didn't lose his memories, but...he was three. He tells himself he was probably wrong about how nice WWX was.
I wonder what will happen when his commands cross a line?
