That matchmaker skill tho.
And it was obvious but there's no way he could chase her as long as he feels he's shit. He won't even entertain the idea of meeting her face to face, so acting on his feelings and hope to ask her out is soooooo out of question until he gets his shit together. Sungah or anyone else for that matter. He'd rather help a chick he likes be happy with someone else. Classic.
But the way it's set, the class rep looks more and more like he'll be the final boss here, for when the MC grows the balls to fight (probably literally) for Sungah or when we get some kind of confirmation that the class rep is not the good guy everyone thinks he is. This being a korean series, I definitely expect Sungah hooking up with her class rep crush at some point with the MC unable to say anything without revealing himself as the bear from ranchat.
