If it's cute thing, I'm okay with it (not because I ship them, just coz I don't want the orange guy to keep harassing our lil' guy) but it's added some SA, nah. And doing something sexual to another person that doesn't consent it or is under the effects of alcohol and drugs is considered rape nowadays, no matter how far they go or whether there is penetration or not.
But to be clear, ff the orange guy is portrait as rival and cut it out with the SA, I'm okay with it (still wouldn't ship them though), but he'd probably stay the same bully-repressed gay-abuser and go over the top with iltak everytime he gets jealous like any other jelly rapist seme
Y'all prepare for some fanservice scenes between Hyunjo and Iltak
