Curious now, anything in manga/anime that has a similar dynamic to the primary trio in Empowered? The MC isn't the dude, it's one of the girls (the nude blond). She gets with her boyfriend at the very start of the story and later invites her best friend (the dark haired girl) to live with them and they grow closer. The romantic conflict isn't about which girl will win but whether or not the second girl will actually formally become a part of the relationship.
