I thought duke esca in a previous chapter said that his family have always had red eyes, which is how he figured out the MC was his biological daughter and how the MC figured out her brother with pink hair was not related to escra bc he didn’t have red eyes. By the manhwas logic, the older brother should have red eyes if he is the biological son of duke escra. Some comments from novel readers have said he is adopted, which makes sense that he doesn’t have duke escra’s red eyes then.
Am I missing something why doesn’t dive’s older brother aka first son of duke escra have red eyes?? Not bio related I guess? But he has the same hair color as dive?
