Maybe I need to reread this manga, but what's the point of the whole White Cat vs Black Dogs thing, and why do they take it so seriously? It's a high school. Do they go their entire lives hating the other faction? If they get into the work force and work with someone from the other faction, do they still hate each other? Why would the older brother take this high school drama so seriously that he wouldn't forgive his own mother if he found out her secret? I get that the whole purpose of this is to have a Romeo and Juliet retelling, but thinking of it realistically it doesn't really make sense.
