Thank you so much!!! I didn't understand it because of the language but I got the gist of the situation. &
I'm so happy to know that Siwon was actually a good brother to Jiwook. It was just that Jiwook was filled with inferiority complex. Gosh! I really wanna see him reep what he's sewn as they say. When he finally opens his eyes and realise that he drove his brother to take his own life. I wanna see him wither with guilt and disgusts as he sees himself! Ugh makes me so angry!
