You can feel however you want and that's okay - I'm not defending or trying to change your mind. But, just so you know...out of respect Korean's refer to upperclassmen or just close friends as older sister/brother.
Very common for a girlfriend to refer to her boyfriend if he is older as Oppa (older brother, too). So, that's not a weird part. It would have been weird if she didn't if they were close.t

Sorry! Didn't mean to double reply!
I don't find it hot since the sibling trope and the forcing onto one another was REALLY weird. Sure they're not related by blood because of what was said in the story but they refer to themselves as so. It's hard to view it in another light that isn't incest. So yeah pretty weird.
