Both of them are. And tbh Cain is a worse case of stalking… he lied to Jooin about his circumstances just so he could stay at the same house as him…. Just because Yahwi is following Jooin home, it doesn’t automatically mean that Cain isn’t a stalker…
Did Yahwi follow Jooin home like 3 times already? In just 2-3days? And some have the nerve say that Cain a stalker.
