You have to be related for it to be incest lol, it's just really taboo/uncomfortable for stepsiblings to be together. And please dont judge the author just because of a manhwa （￣へ￣）
blood related or adopted related, they’re still siblings. the author is messed up if they end up putting them together.
Are we reading the same thing? They grew up apart from each other, even in her past life they were not close. If you don't like it then stop reading instead of insulting the author
incest vibes LOL. for those who say it’s not incest, you’re completely wrong because it is. it doesn’t matter if your adopted or not, that is your sibling. the creator definitely has some incest fetish (￣∇￣")
