attention.
maybe he was trying to seek attention from that four-eyed prof.
It seemed as though he hurt himself so that he wouldn't hurt someone else.
Yeah that's the way I read it too.
uhmm now that I read it again, it seems to make more sense that he was trying to hold himself against hurting others.
There was this line from Hyeongjo "...Hyung doesn't like it when I hurt others. Well, (looking at his injured hand) thanks to this I'm in a much better mood now"
then the black haired guy (forgot his name lol) thought to himself "No matter how good you are saying it is, why do you have to take it this far just because there are people getting closer to the person you like?"
But anw thansk for your help :)
someone please enlighten me.... why did Seo Hyeongjo (the blonde dude) hurt his hand?? What exactly is he trying to hold back? His desire to hit other people? His sexual frustration??? Σ( ￣□￣||)
