He did threaten Yule with that. Kyungsoo told him that if Yule "meddle with his affairs again" he'll drop dead right before his eyes. It's in chapter 47.
And He had a Breakdown on the same chapter, He was going to trust Yule and open to him (not exactly forgiving him), but then He found out He did to him more or less the same as 3 year ago (this time without watching, and "only" 1 rapist).
I think this is why He stopped being afraid for DongHyuk's life and couldn't endure it anymore so He scaped. Only to regret it and face more abuse and fear as ever.
Poor Kyungso!!
true true, i forgot that he did have a nervous breakdown, and he did threat him with suicide, and that is how he actually managed to get away in the first place, sucks that he didn't get far enough to scape the spider web, but it is understandable if we consider his level of isolation, but he keeps bouncing back and gets knocked down right away, maybe the only scape could be if yule dies somehow, i mean even if kyungso won't snap and kill him, yule is in that line of work and with his charming personality he must have rubbed a couple of ppl wrong, somehow i don't think he is destined to die of old age, what do you think?
I always thought that Yule probably kept watching over dongHyuk while He had Kyungsoo living with him (maybe He asked his Rape-bros to do it, so if Kyungsoo ever ran away, He'll find him quickly). It would make sense for him to be prepared for this since He didn't expect Kyungsoo to run away the first time, and expended 3 years looking for him.
I was hoping at some point that the brother would kill Yule and make it look like an accident... XDDD He has the means.... but probably He hasn't done it because of the sister.
oh i totally overlooked the older brother, since kyungsoo reminds him of his mother he might just be his get out of jail card, i don't think he could give blondie a happy ending but he could give him an oversea ticket and some money to start anew, he owns him way more than that, also its been bugging me that the puppy seme actually knows were yule and kyungsoo lives :B
this webcomic is making me numb, i don't get surprised, shocked, and my empathy is fading away, but i can't stop myself of wait for the aftermath of this train wreck, i still don't get how the mc has not mentally broken down and or attempted suicide yet, because against yule his only leverage is himself, its such a pity he doesn't use it, i could love to see yule terrified at the prospect of losing him for good
