here's a 45 secs teaser.
thanks to Coconut milk of sjs thread @ soompi for the downloadable link that she provided.
from the teaser, it looks to be a heavy drama. i hope that ji sub's character will not die here like his two other dramas : 'What Happened in Bali' and 'I'm Sorry, I Love You'.
'cain and abel' also stars Shin Hyun Joon [Stairways to Heaven], Han Ji Min [Capital Scandal], and Chae Jung Ahn.
