plus its not like Issei is adding girls in to his harem all whily nily.. im sure he doesnt even realize he has a harem at this point, while the girls do. He still isnt mature enough to try to charm over a girl, plus it would ruin his character if he was a playboy like that.. its better that girls get attracted to him on their own by seeing Issei with their own eyes and having that change in their feelings for him
