Let's talk about Cheon Ill-do's secret weapon

One point has always caught my attention since it was mentioned at the end of Season 1. Juro said that the Left Hand's kids could handle the Right Hand's kids... which leads to the question: Does Choi Min-wook also have a group of young assassins, in addition to his large army of bodyguards led by Ma Hakyoug? And is Juro confident that his boys can handle them? But Cheon Ill-do knows he wouldn't stand a chance in a direct battle against Ma Hakyoug and his guards, so Cheon Ill-do is using Kim Shin to deal with Ma Hakyoug while his Fingers attack Choi Min-wook. Are Kim Shin and Choi Min-wook underestimating Cheon Ill-do too much, focusing on each other? Or do they both have plans to deal with Cheon Ill-do?
