"The only taste you need to know is mine."

A chance reunion after 10 years for Hiro and Kiriya. They were "kiss-friends" during their last summer of high school: a memory from the past which Hiro wants to forget. However, even after turning 27, his memory of those times keeps binding him to the point he can't date anyone. Kiriya on the other hand, even after the reunion, kept his cool, but… These cool men intense feelings are welling up!
