Yule almost kills himself because Dong-hyuk was holding a knife on Kyung-soo and saying he was gonna kill Kyung-soo so Yule couldn't have him (?) I'm not sure, because I don't read Korea but that's all I understood. Yule didn't die thought, he lived but Kyung-soo didn't stay whit him or Dong-hyuk. Dong-hyuk is gonna be so crazy that everyone will hate him... But we can't forget that he has gone through some drama as well as Kyung-soo (not as much but still a little)
How can someone just become a roll..?
