maybe because its literally borderline incest??
they call eachother brother and sister in majority of the manhwa, plus they look so similar like its just gives me the ick
if they didnt mention they werent blood related at the start, i was would've genuinely thought this was incest and the male lead just feels so creepy for some reason
It's not even borderline, what are you talking about lol
They're not related. Therefore it literally does not matter what they call each other. You guys are just silly freaking out over words.
Cesare is a creep through and through, I'll give you that though.
Ngl the way some readers see incest in everything and freak themselves out is really bizarre.
