Or he can learn a thing or two about dojin from others.
He's going to learn about Dojin from his enemy though. I think that dude Hyesung clung to is Dojin's some kind of childhood acquaintance who sees themselves as rivals (plus I'm pretty sure he's jealous of Dojin or feels inferior to Dojin judging with how he reacted when Hyesung mentioned Dojin's name or family).
Ah that's true.
welp. The only thing that went inside my head was "Protecting yourself from Dojin is useless now, Hyesung. Because he won't look for you anymore." So, pimping himself to strangers is sadly all in vain.
