Well, it is no wonder they weren't able to produce a fourth season because the Studio producing Junjo was busy producing Super Lovers 1 + 2. I don't mind that it takes some time because I know it is going to be good! When you compare the animation quality from Super Lovers Season 1 to Season 2, you will notice they improved the animation, artwork and quality a lot! So it is safe to say Junjo Romantica Season 4 will have a much better animation quality than the former seasons.
