Missed Potential :/

I really love the original Kabukichou Bad Trip story so when I saw the spin-off was finally translated, I was excited. I really do like the new couple's relationship and it does make sense but I really wished it wasn't just relegated to just one short volume when there's so much to explore for these characters in terms of trauma and such. Despite the shortcomings it had, I still really enjoyed the story and the characters, especially Rio.
