Aranel's manga / #Brother complex(2)

Constantly confused on if the older brothers feelings are romantic love or not, hoping this is because of slight miss translation and not that this is how the writer wrote it. Edit: ok so the brothers feelings were romantic (find this out when you meet the ex) however the brothers are not blood related and meet each other when they are older (still kids but not when they are like 1 or 2) so it is more understandable that the older brothers could develop romantic feelings. By law they are brothers however I'm not as uncomfortable now I know they aren't related by blood.
