Aside from In-hun's bastardness, can we take a pause to seal the moment where Seungho marked NK with the red dot? Maybe I'm just reading too much into this but, this may be Seungho marking NK with the start of gaining knowledge or maybe he's just showing off how pretty NK is (as forehead decors used to be a beauty symbol in ancient China). I don't know. Haha! Let's add to the fact that the red dot symbolizes marriage in India.
Kyaaaaah!!!! ε=ε=(ノ≧∇≦)ノ
