...that's too much twist...
nah, he' s Hwon
....tru
My theory is he opposite... I reckon hwon is his childhood friend, the one that got left behind, and for some reason I think the " begger" is the step brother. Or the bigger got killed by hwon that day, so he had to go to juvie....
Ughhh~ too much possibilities!!~~~~~~
when I read it before I thought that to just by the looks but since I have no clue and not much evidence that's all I could really say
This is just a theorie I made up but I think Woojin's childhood friend ( the one who got beat up by the one they call beggar ) is his step brother but I'm just guessing.
