I came to believe that Dark Blue Kiss was made just to settle conflicts and fights between Pete and Kao and develop Sun and Mork, which is even one of the only things that are worthwhile here. Many fights that I believe were unnecessary ... But it sends important messages along the plot, and that is a great factor. The cast is even captivating and the soundtrack is not the most striking nor the most engaging but it manages to fulfill its mission in the series. But I believe that the PeteKao story was more interesting in Kiss Me and Kiss Me Again.
