The MC is currently nowhere near YWoong. He's not that far behind the rest of the class considering even at the beginning of this arc it took TYoung going all out to beat him, so obviously his hax eyesight will allow him to progress fast. But YWoong is nearly Ha-min level, he was able to land a pretty good shot on Maria. The MC might be able to fight him in two arcs time, but he is definitely not the next stepping stone, since that will mean the MC will leapfrog basically the entire class.
