Comment by Yep i am not. on Candy Man - Chapter 15

I think he does. Because he didn't only grin last time. But when he said he was talking to Kyuri last despite his phone being off I think is an allusion to him knowing. Since he was taking to Kyuyeon at the time which means he was talking to Kyuri at the time. Which means he has to know just my guess though.
