Ok...guys...here me out... So i think that kimdan isn't behaving like last time during their s** scenes, cus last time he kept on complaining about how much it hurt and all. But, now he is just going with very thing mr joo says since ep 30 or something. So its quite obvious that he's got feelings with jaekyung. And Jaekyung is probably ashamed of what he did to kimdan at ep34 cus we just got his first pov in this  whole manga ever
