I believe  it needs a 2nd season has there is more to the story that can't be done season 1 only covers 4 volumes and there is 10 volumes to cover The reason why season 1 is so hated is because all the sexual assault But season 2 wouldn't have that season 2 would be better and focus on relationships has in the Manga the first 4 volumes contain sexual assault while the rest doesn't contain nearly has much
