Almost balanced. When Sakura makes her character, ideally male or a very persistent female that will turn Melanie bisexual, we would need a hetero/bisexual female so the all hetero male cast members have a potential lover. Then the last two hopefully will balance out. It would be cool if we had a gay male couple. Just saying xD. Though...one would need to be bisexual or closeted since they'll be in a love triangle.
