Damien already knew from early in she wasn’t his sister tho and not to mention if you find them getting together weird than you’d also have to find childhood friends getting together weird. The ones where they’ve been friends since they were in diapers cuz there’s lowkey no difference between that and this
There is a difference tho. They consider themselfs friends and with addopted sister you consider her a sister. The mc/boy didnt knew she wasnt her sister he was just suspicious be still considered her a sister and started to care for her and the girl/mc considered him as her brother as well. So them getting together is weird ad flip. And bad as well
Some country, marrying your stepbrother/sister are legal lol
And they didn't adopt her, his mother literally kidnapped/saved(?) MC.
They didn't treat each other like siblings and focus on surviving. They even know that both of them aren't siblings.
Kind of dumb of you to not understand this.
Just because they lived in the same household doesn't mean they are siblings.
No matter i support and ship and no judgement because they not literally brother and sister...
