i think he does know about yuki? bc he interrupted wang when he was right about to rape yuki. not sure if it was intentional but even if it was on accident, I think he knows that yuki is affiliated w/ wang now

I think Rei acts as a double spy. He stays with Wang to avenge his older half-brother. Then, his lover acts to maneuver the Rei's vengeance for his father and his sister. What a complicated and entangling drama. I hope he will know about his half-nephew whereabouts.
