Ahahahahah
Same here! Though I still don't get why am I even feading this, it gives me creeps every time, ugh. Guess, I stayed for the plot twists and beautiful drawing style.
As about the uncle... I think Sangwoo might be angry with Bum for hiding it, but I feel like he will just ask Bum why he didn't tell it earlier and then will fucking find the bastard and slice him into pisses (or make Bum do it).
Have you read chapter 25?
read it on lezhin, it was available since thursday.
Well i think there were people who posted links in the comment section :)

Well fuck EACH FUCKING CHAPTER ITS LIKE THIS : 1- I FUCKING HATE SANGWOO 2- I guess he isn't that bad.. 3-YOU FUCKED UUUUUP. And also what do you guys think, how will Sangwoo react to Bum telling him that he was raped each day by his one and only UNCLE!! FIND ON THE NEXT EPISODE WITH THE 3 SAME FUCKING STEPS!!
