After being trained by this webtoon to expect a male lead here to take advantage of and treat jooin like absolute garbage, including but not limited to r*pe (looking at you yawhi), I was actually pleasantly surprised. Cain made a mistake by kissing jooin when he was sick and not able to consent properly, but not only does he acknowledge that but then his thoughts are to apologize first and thinking about the best course of action to make sure jooin isn't uncomfortable, wow imagine actually having a conscience and taking jooin's feelings into account...I'm on board with this!
If it had been yahwi y'all just KNOW he would have kissed jooin without consent PURPOSEFULLY

I haven't been able to find the raws so I'm not sure on what the actual circumstance IS, but it's NOT an incest story. She's either called him Oppa and it's been directly translated to 'older brother' or it's relation through marriage i.e. step siblings which is not incest as they're not related.
Also, MAYBE SPOILER SO LOOK AWAY
but I'm SO happy that the male lead is the fourth prince with the mint hair, Amor! I'm a little tired of the toxic villainous murderous dark prince getting the girl, and although Amor gave me second lead vibes I'm excited to see him as the lead!

Incest is, as a general rule, sexual relations between strictly blood relatives (consanguinity as you've mentioned), and although it only sometimes can apply to relatives connected through marriage (e.g. step siblings), that generally only applies as 'incest' when, for example, the relationship is that of actuals siblings, i.e. the siblings have grown up as siblings and effectively share a genuine sibling relationship.
Just want to be clear in saying I am in NO way trying to justify any incest because I steer CLEAR from those stories believe me, but this just isn't that case at this point fortunately. If it is later revealed they are actually blood related I will be dropping this, but from what we've seen I don't believe they share blood relation. Fingers crossed :')

I'm absolutely shocked to still see so many people supporting Hwan. Are y'all forgetting that not only has he been sending monster after monster to r*pe Chiwoo so that he only has Hwan to rely on, but also is the direct reason for the death of Chiwoo's parents, again just so that he can have Chiwoo all to himself. Not boyfriend material in my personal opinion but each to their own I guess
╮( ̄▽ ̄)╭

I saw someone saying "he didn't knew when he sended the monsters" which means people are either naive or are not reading properly. Jun was the First created and was made with no powers to look like a normal human and find sunny's contractor, which he didn't knew for a long time it was Chiwoo. Hwan was already sending monsters to rape Chiwoo even before knowing Chiwoo's was with Sunny, he just wanted to fuck Chiwoo up, quite literally.

I just re-read chapter 40 where it's revealed and until I'm explicitly shown it to not be the case I'm still convinced Hwan is the one who made the wish to murder Chiwoo's parents. It could later be revealed to not be the case, but the scene itself overwhelmingly points to that as the case (regardless man's still fucked up though)

I just went back and read the first episode compared to now, and why has Yul literally become a child....? Before it was two grown men fucking (albeit one of them petite) and now it's a literal child. Not to mention the absolutely creepy sexual tension ebtween the broths and SPOILER ALERT KINDA BUT NOT REALLY I read a few chapters ahead in the Korean raws and there's even more weird incest tension between Luan's twin brother/sister duo. WHAT IS HAPPENING

I know, right! I'm trying to figure out Wtf is going on, too. Why was the twin brother sleeping with his sister's look a like, for 2 years? Why is J constantly trying to tempt Woohyun into some sexual position? And even tho Yul is supposed to be over 19yo, why is he so disconnected from reality? I mean, social isolation, and abuse aside, he is mentally underdeveloped, much as he is physically. Idk. Just reread this, and I'm still a bit confused.

LITERALLY I just reread the series up to now and to the most recent Korean raws and this went from a fairly straightforward concept of "petite man is being entrapped in a house and essentially milked for his musical talent, is saved by powerful CEO" to a wild borderline incestuous and shotacon-like man + child looking dynamic and I'm just...HUH what happened

guys...I'm scared. The author has made Yahwi into such an asshole that I'm firmly on the lovable Cain's team...but unfortunately these kind of stories generally end up with the asshole seme getting the guy....and leaving those of us with second lead syndrome heart broken
So that must mean the author has to make Cain look even worse somehow. I'm worried the author is going to make Cain possessive or bad somehow to compensate for Yahwi and make him look like an option again somehow
Y'ALL I'M SCARED FOR OUR BOY
You had me in the first half, not gonna lie :')
Thank goodness, a happy ending for our boys <3
