Overall, I enjoyed this movie, but there was one thing that left me unsatisfied. In several scenes, the female lead (Kenzaki Hiruko) promised to let the male lead (Yuzuru Hamura) kiss her if he did what she asked. This situation happened again when Kenzaki Hiruko ordered Yuzuru Hamura to move the zombie body of Shindo Ayumu from the bed. After that, I thought and hoped there would be a scene where Kenzaki Hiruko would fulfill her promise at the end or before the movie ended. But that didn't happen, and they didn't even slightly mention the promise. Instead, they only showed a scene revealing that Kyosuke Akechi had become a zombie. It was OBVIOUS that he wouldn't survive, and it didn't surprise me at all. I'm sure if the director had decided to include a scene, even just a slight reference to the promised kiss at the end of the movie, many people would have liked it as I did. That's why I call it "Owing Him a Kiss" because it remains a debt. That's my brief review and complaints, thank you.
